1. Integrating GPS
Pool Service
and the Customer
sm

2. • Review of the benefits of GPS
• Digital BlueTooth Devices can be linked to Smart Phone/GPS
• Smart pool Service & Water Testing is now possible
• How to get best accuracy with your testing
• Changes that may effect Pool Industry because of CDC’s
(Center for Disease Control) Model Aquatic Health Code
(MAHC) and the NSF 50 and WQTD (Water Quality Test
Device) performance certification
Topics for Today

3. • Global Positioning System is a “constellation” of 24
satellites that orbit the Earth and make it possible for
people with ground receivers to pinpoint their
geographic location.
• The location accuracy is anywhere from 300 to 30 feet
for most equipment.
GPS DEFINED

5.  Improved safety
 Reduced fuel costs
 Reduced operational costs
 Increased productivity
 Reduced liability issues
 Reduced idle times, improved routing and customer
service
 It can Increase the number of customers you can
handle
BENEFITS OF USING GPS

6. Benefits of GPS
 Smart Phone is best way to keep track of your
Serviced Customers
 GPS link in your Smart phone (or device) offers best
way to travel to Customer
 Custom Software can link GPS to optimize Service
Technicians travel, duties, and time
 Pool Water Test Photometers can now be linked
effortlessly by BlueTooth to Smart Phone and GPS

7. • Pool maintenance requires testing for
Balanced Water
• Commercial Pool Testing must meet
Health Department requirements
• Free Available Chlorine and pH for
Commercial Pools must be tested as often
as every 2 hours per MAHC (Model
Aquatic Health Code)
• The pool industry is evolving and properly
trained Pool Service Technicians are
needed. Using high tech devices can
make it all more efficient.
What is Smart pool testing?

8. Smart Pool Testing
 Many Pool devices and controls have BlueTooth or
Smart Phone communication
 Pool Controllers have option through WiFi to Monitor
and Adjust pool chemistry via Smart Phone
 Similarly Temperature control via WiFI of Pool or Spa
 iDip is a Photometer with a BlueTooth link to Smart
phone (iPhone, iPad, Smart Phone) that will keep
track of your water testing, location, and service
details.

9. Smart Pool Service
 First step is to train the Service Technician and keep
him trained
 Smart tools are great but don’t work too well in
untrained hands
 There can be a lot of assumptions that everyone
knows how and what to do
 This can breed ERRORS

10. Smart Pool Service: Train so they
can UNDERSTAND
 Understand the basic fundamentals of Testing
 Understand the different test methods
 Understand how to run the test properly
 Understand limitations of each test
 Understand that test reagents have shelf life even
when no expiration date is listed

11. Smart Pool Service: Train so they
can UNDERSTAND
 Understand that quality results
require your attention to details
 Understand how you can verify your accuracy
 Understand that an initial OJT (on the job training)
with occasional reviews approach can have problems
such as:
 Initial training fades;
 OJT usually involves avoidable mistakes;
 No proficiency guarantee

12. Smart Pool Service: Train so they
can UNDERSTAND
 Understand that best retention happens when
training is regular and short (1 hour)
 Understand how to use the best communicators in
your group as experts.
 Understand the benefit of Visual and Verbal
communication
 Understand the benefits of proficiency, tracking it,
and the value of incentives
 Understand the value of keeping UP TO DATE of
where our industry is heading

13. For Visual COLOR Match TESTS
• WHEN test involves visual color
matching then there is the small but
real issue of color blindness
• Are YOU color blind?

14. COLOR BLINDNESS
Over 32 million Americans (8% of men) are color blind

15. Understand TEST Resolution and Accuracy
• Test resolutioncorrelates to test accuracy
• Digital Devices give best resolution
• After 40 years as a Chemist I personally have come to
a realization that my lab equipment if properly
calibrated (precision is good) will typically give an
accuracy of about 3 times the resolution of the test

16. RESOLUTION EFFECTS ACCURACY!
Resolution 1 ppm Resolution 0.1 ppm

17. RESOLUTION EFFECTS ACCURACY!
If your Digital Device has a resolution of 0.01 ppm for
Free and Total Chlorine then an accuracy of +/- 0.03
ppm can be expected (factory calibrated photometer).
Accuracy is most important when you measure the
Combined Chlorine levels, since they need to be below
0.4 ppm (MAHC recommendation). Higher levels
trigger:
1. Superchlorination (Shock)
2. Water exchange or
3. Patron adherence to better BATHER hygiene

26. COLORIMETIC/PHOTOMETRIC
DIGITAL TEST DEVICES

27. • Using colorimetric or precipitation
chemistries and the color
(or precipitate) is measured by a
digital instrument that measures
light transmission through the sample
• Concentration is determined by the amount of light that is
transmitted through the reacted pool water sample
• Chlorine has 0.01 ppm resolution; +/-0.04 ppm accuracy
• pH has 0.1 ppm resolution; +/- 0.3 ppm or better accuracy

40. Understand how
TO CONFIRM ACCURACY
OF YOUR TEST METHOD OR DEVICE

41. • Standards are solutions with known
values that are used by laboratories to
verify the accuracy of their test
• If you are using a pH meter you already
use pH Standards
• Standards are now available for pool
service professionals
Understand WHAT IS A
“STANDARD?”

42. • Verifies the accuracy of your test
• Verifies operator is running test correctly
• Verifies reagents are functioning properly
• Verifies Digital Device accuracy
• Required for Digital pH meter calibration
Understand WHY USE A
“STANDARD?”

43. • Food, Medical, and Drinking Water Agencies
(Government regulators and inspectors) require
that testing equipment be confirmed by Standards
regularly
• Understand that using Standards gives confidence
in what you are doing
Understand WHY USE A
“STANDARD?”

44. • Most Standards are for only one parameter and require
dilution to your testing range (like pH 7.00 Standard)
• Ready Snap 1P requires no dilution to use; just twist open,
fill test cell with sample, and run test to verify accuracy
• Ready Snap are Plastic Ampoules that contain 10 ml of
POOL WATER Standard with known values and they can
be used with most pool tests
• NSF 50 and the MAHC do not require using Standards
• Wouldn’t you like to know if your results are accurate?
EXAMPLES OF
STANDARDS

45. • Turn on the Photometer and
rinse out photometer cell three
times with clean water
• Break open a Ready Snap by
twisting the top 180°
Using READY SNAP With a PHOTOMETER
STEP 1

46. • Squeeze plastic ampoule to
fill photometer cell to
capacity (4mL)
• Discard this liquid sample
followed with a little shake of
the meter to empty the
photometer cell of the
remaining water drops
• Squeeze plastic ampoule to
fill the photometer cell again
Using READY SNAP With a PHOTOMETER
STEP 2

47. • Select the MENU for the
test method procedure you
want to verify (Calcium
Hardness in this example)
and run the test method as
you would normally do the
test
Using READY SNAP With PHOTOMETER
STEP 3

48.  Compare the Photometer
Digital Display against the
assigned value in the chart
provided with Ready Snap
Standard
Using READY SNAP With a PHOTOMETER
STEP 4

49. • If your value is
within the
acceptable range,
you are operating
the photometer
correctly for the
Calcium test
method
• If your value is
borderline, review
that you are doing
the test properly
Using READY SNAP With a PHOTOMETER
STEP 5

50. •Total Alkalinity
•pH
•Calcium Hardness
•Copper
•Cyanuric Acid
•Phosphate
•Salt
USE READY SNAP STANDARD FOR
VERIFYING THESE TESTS:

51. Understand BALANCED WATER
• Healthy Water = Balanced Water
• For balanced water 6 parameters to consider and they
are used to calculate (Langelier) Saturation Index
1) pH
2) Total Alkalinity
3) Calcium Hardness
4) Total Dissolved Solids (TDS)
5) Temperature
6) Cyanuric Acid (CY)

52. IDEAL LEVELS FOR POOLS
TEST IDEAL LEVELS
pH 7.4 to 7.6 (MAHC 7.2 to 7.8)
Free Chlorine 1.0 - 3.0 ppm (Maximum of 10 ppm)
Cyanuric Acid 20 to 60 ppm (MAHC below 100 ppm)
Total Alkalinity 80 to 120 ppm (MAHC 60 to 180)
Calcium Hardness 200 to 400 ppm (MAHC maximum level is
1000 ppm)
Copper/Silver 1.3 ppm/0.10 ppm (from MAHC)
Saturation Index -0.5 to +0.5 (salt pools -0.2 to +0.2)
Combined Chlorine 0.2 ppm (MAHC action level is 0.4 ppm)

53. • Balanced Water is water that will neither scale nor
corrode pool or spa surfaces and/or equipment
• Corrosion is the dissolving or wearing-away of pool
wall, pipes or equipment (SI below 0.0)
• Scale is the white deposit or precipitate that builds up
on fixtures, surfaces, & equipment (SI above 0.0)
• Balanced water is non-irritating to eyes & skin of
bathers, & allows sanitizer to work effectively
• SI is perfect when 0 but OK best between -0.5 to +0.5;
FOR SALT POOLS -0.2 TO +0.2
BALANCED WATER

54. • If pH goes up then Calcium
Hardness and Alkalinity has to be
kept at lower (200 for CA & 80 for
AL)
• Danger signs – pH above 7.8 and TA
above 120
SI and RELATIONSHIP OF
BALANCED WATER

55. SI (LSI)

56. BlueTooth iDip Calculates SI
 Now you can have the benefit of knowing Saturation
Index (SI) value automatically without effort
 Just test the basic four tests of pH, Calcium Hardness,
Total Alkalinity, and enter the Temperature and TDS
of the pool and iDip App Auto Calculates the SI

57. BlueTooth iDip Links to GPS via
BlueTooth and your Smart Phone
 Now you can have the benefit of documenting all
your testing including Saturation Index (SI) value
automatically without effort by way of iDip App
 All this data is stamped with GPS coordinates and the
App allows you to immediately link your Customer
with this data and any entered notes by way of an
email.
 Can Service be any better then this?

58. • Circulate pool water before collecting
sample, or manually stir water in sample
area
• Rinse sample cell/vial at least three times
with pool water before sampling
• Sample water 18 inches below surface
(recommended for tests like Chlorine and
Bromine)
TESTING
Best Practices

59. • Do not collect water sample near
return lines
• Note the temperature of water to
be tested (Very cold or very hot
water can effect test results)
• Read test instructions for
procedure how to run test with
very cold or very hot water
TESTING
Best Practices

60. • Perform tests as soon as
possible after collecting sample
(immediate testing is required
for accurate Free Chlorine and
Bromine results)
• If collecting samples for later
testing, handle carefully to avoid
contamination, fill bottle to
capacity, & seal sample bottle
tightly
TESTING
Best Practices

61. • Pay careful attention to
expiration dates on
reagents and test strips
• Keep reagent containers tightly
capped and store in a cool, dark
place when possible.
• Don't swap/mix the caps on
reagent bottles to avoid
chemical cross contamination
TESTING
Best Practices

62. • Where required, measure
volume of water sample to be
tested (Measure the bottom of
sample meniscus, not the top at
fill mark)
• Don't interchange sample vials
or cells
• Follow manufacturer’s test
directions carefully
TESTING
Best Practices

63. • Add liquid reagents
carefully – make sure the
correct number of drops
are added to sample and
drops are equal and full-
sized
• Mix reagents with test
samples thoroughly
TESTING
Best Practices

64. • Record results and maintain those
records for each pool or spa
• Never dispose of tested
samples/reagents in the pool
• Rinse sample test vials and cells
immediately after testing
TESTING
Best Practices

65. • When using a photometer or any test,
verify the accuracy of your results: use a
Pool Water Standard to verify photometer,
reagents, and operator
TESTING
Best Practices

66. • Where possible use simple tests
• Digital devices give best resolution
• Better resolution gives better
accuracy
• Accurate results help to make best
choices for pool maintenance
