RINSE & FILL CELL WITH SAMPLE
3
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 with
the water sample. Tilt meter to discard about 0.2mL water to leave room for liquid reagent.
Follow the steps to 'SELECT CUSTOMER' & 'CONNECT DEVICE VIA BLUETOOTH' before
proceeding (see page 8).
ADD DROPS

Aluminum, Ammonia & Sulfide (SPECIAL NOTES)
Aluminum — A. First, clean the CELL with 0.1N HCl, Distilled Vinegar (5%), or Muriatic Acid before
1
filling the meter with the sample to be tested. B. If running multiple tests in a row, using the same
water sample, the CELL does not have to be rinsed or cleaned with acid between each test. It is
recommended that the CELL be rinsed 3 times with the sample water.
Ammonia — The calibration of the meter is based on a water temperature between 14°C (57°F) and
2
28°C (82°F). If temperature is below 14°C (57°F), your final Ammonia value may read low.
Sulfide — A. For results as Hydrogen Sulfide (H2S), multiply the resulting value by 1.06. B. The
3
calibration of the meter is based on the water sample temperature above 20°C (68°F). If the water
sample is below 20°C (68°F), the strip has to dip in the sample for an additional 10 seconds.
