Water tests for the field and the lab: Hanna individual test kits by titration, checker disc or colorimetric method for parameters such as acidity, ammonia and chlorine, LaMotte Insta-Test strips, and LaMotte digestion tubes for total nitrogen and total phosphorus.
Low TP: 0–3.5 mg/L | High TP: 0–100 mg/L | Method: Persulfate digestion | 25 tubes/package | Requires COD Heater Block (5-0102) + COD Adapter (1724)
Parameter: Acidity (As CaCO3) | Method: Titration | Smallest Increment: 1 mg/L; 5 mg/L | Chemical Method: Methyl-Orange / Phenolphthalein
Values: 4, 5, 6, 7, 8, 9, 10 ppm
Quick chemistry for water in the field or the lab. Hanna individual test kits each cover one parameter, such as acidity, ammonia nitrogen or free and total chlorine, by titration, checker disc or colorimetric method, with 50 to 200 tests per kit. LaMotte Insta-Test strips read alkalinity, chlorine, chlorine dioxide and other parameters with no reagents, from a pop-up container, for drinking water, food, beverage and pool work. For nutrients, LaMotte digestion tubes measure total phosphorus (0 to 3.5 or 0 to 100 mg/L) and total nitrogen: the tubes are reacted in a heater block, then read on a colorimeter or spectrophotometer.
A strip gives a fast reading with no reagents. A titration or checker-disc kit measures one parameter in set steps, such as 1 or 5 mg/L for the acidity kit. For continuous readings or several parameters at once, use a water quality meter.
A COD heater block and a COD adapter to react the tubes, then a colorimeter or spectrophotometer to read them. They ship as small-quantity hazardous materials, 25 tubes to a package.
Hanna checker-disc kits read free chlorine from 0.00 to 0.70 or 0.0 to 3.5 mg/L, and colorimetric and free-and-total versions are listed; LaMotte Insta-Test strips cover chlorine and chlorine dioxide.
