Ammonia Low Range Checker
The HI-700 Ammonia Low Range Checker is a simple, accurate and cost effective way to measure low ranges of ammonia in fresh water.
Designed as a more accurate alternative to chemical test kits, the HI-700 provides quick, accurate results in four easy steps.
HI-700 uses an adaptation of the ASTM Manual of Water and Environmental Technology, D1426-92, Nessler method. The reaction between ammonia and reagents causes a yellow tint in the sample.
