Palintest Ammonia photometer tablets (indophenol method) give fast, accurate measurement of ammonia in drinking water, wastewater and environmental samples, over a range of 0 to 1.0 mg/L N. Each pack contains 250 individually foil-sealed tablets for use with Palintest photometers that include the ammonia test, such as the Lumiso range. When testing sea water or brackish water, use with Palintest Ammonia Conditioning Reagent (AT170) to prevent salts precipitating in the sample.
