GPS and Bluetooth devices allow pool service technicians to efficiently track locations visited and test results. New regulations from the CDC require more frequent water testing for commercial pools. Using digital testing devices connected to smartphones via Bluetooth provides accurate test results that are automatically logged with date, time, and location for each pool serviced. Standards solutions verify that testing devices and technicians are obtaining accurate measurements.

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

- 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

- 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.
