The Professional Series are distinguished by the accuracy of liquid to-liquid colorimetric testing, 2 oz. reagents, an electronic Watergram Water Balance Calculator, and attaché-style carrying cases. Taylor Slide Comparators are systems for colorimetrically determining solute levels in industrial, natural, and recreational waters. In each test, a liquid sample is treated with reagents causing a color to develop. The treated sample is then placed in the comparator base and compared to the liquid color standards in the Slide. A color match is made and the concentration of the substance is read from the values on the Slide. The unique Taylor colorimetric system compensates for cloudy or colored samples by using three cells. Two untreated samples are positioned on both sides of the treated sample, providing a more accurate color match.

4. Add R-0009 Sulfuric Acid .12N dropwise. After each drop, count and swirl to mix until color changes from green to red.

5. Multiply drops in Step 4 by 10. Record as parts per million (ppm) total alkalinity as calcium carbonate.

Calcium Hardness Test

1. Rinse and fill sample tube (#9198) to 25 mL mark with water to be tested.*

2. Add 20 drops R-0010 Calcium Buffer. Swirl to mix.

3. Add 5 drops R-0011L Calcium Indicator Liquid.Swirl to mix. If calcium hardness is present, sample will turn red.

4. Add R-0012 Hardness Reagent dropwise. After each drop, count and swirl to mix until color changes from red to blue.

5. Multiply drops in Step 4 by 10. Record as parts per million (ppm) calcium hardness (CH) as calcium carbonate.

Total Hardness Test

1. Rinse and fill sample tube (#9198) to 25 mL mark with water to be tested.

2. Add 10 drops R-0854 Total Hardness Reagent. Swirl to mix. If total hardness is present, sample will turn red.

3. Add R-0012 Hardness Reagent dropwise. After each drop, count and swirl to mix until color changes from red to blue.

4. Multiply drops in Step 3 by 10. Record as parts per million (ppm) total hardness (TH) as calcium carbonate.

Magnesium Hardness Test

1. Subtract CH from TH. Record as ppm magnesium hardness (MH) as calcium carbonate. Formula: TH - CH = MH.

Cyanuric Acid Test

1. Rinse and fill CYA dispensing bottle (#9194) to 15 mL mark with water to be tested.

2. Add R-0013 Cyanuric Acid Reagent to neck. Cap and mix for 30 seconds.
