The HI-700 Ammonia Low Range Checker offers a simple, precise, and affordable way to measure low concentrations of ammonia in freshwater.
Designed as a superior alternative to traditional chemical test kits, this compact device delivers quick and reliable results in just four easy steps. It operates using an adaptation of the ASTM Manual of Water and Environmental Technology (D1426-92, Nessler method), where the reaction between ammonia and the reagents produces a yellow-tinted sample.
