pH Test Reagent

pH Test Procedure

1. REMOVE STRIP
   Remove one (1) eXact® Strip Micro PH, Part No. 486639 from the bottle before beginning the test. Set the strip in a dry, convenient place and recap the bottle immediately.
2. TURN METER ON
   Press the ZERO/ON button to power the meter on; the display will show all annunciators, then the current MENU selection, followed by the last reading.
3. SELECT TEST: PH2
   Press and re-press the MENU button until the display shows the parameter PH2.
4. FILL METER WITH SAMPLE
   Rinse the CELL at least 3 times with the water sample you will be testing - rinsing minimizes the potential for cross-contamination from a previous test. Finally, fill cell to capacity (4ml) with the water sample.
5. ZERO METER
   Press the ZERO/ON button. When the display shows 0.0 PH, the sample is ready for testing.
6. DIP STRIP AND PRESS "READ"
   Dip the eXact® Strip Micro PH, Part No. 486639 into the CELL and immediately press READ. This starts the 20 SECOND countdown timer. During this time move the strip in a gentle back and forth motion. Remove and discard the strip after "1" on the display disappears (if water temperature is above 100°F/38°C remove and discard the strip when the time displays 15, countdown continues). The cursor will move across the display while the meter prepares to measure the sample. Record result displayed (this result is automatically stored in PH2). After testing, rinse cell immediately. NOTE: For best results, Total Alkalinity of the sample should be 40-140 ppm. PH2: pH reacts with Phenol
   Red, which is yellow at pH 6.1, but forms a red color as the pH level rises. Maximum red is at about pH 8.4.
