描述

Desiccant vial with flip-top lid Waterproof color chart 25 test strips Measuring field: 0, 10, 25, 50, 100 ppm Low Level Ammonia Test Strip, 100ppm This test strip detects ammonia in increments of 0, 10, 25, 50, and 100ppm. The Low Level Ammonia test strip is designed to work for the detection of ammonia (NH3/NH4+) in water. The strip is composed of two filter pads. The first filter pad acts as an absorbent and takes up the water sample. The first pad has been treated with alkaline materials. This alkaline environment converts any ammonia to the gaseous state. The second filter pad is an hydrophobic material that has been treated in such a manner that only the gaseous ammonia is absorbed by the second filter pad. The second filter pad contains an indicator(s) capable of detecting the gaseous ammonia through a change in the pH of the filter pad.
