The HI-733 Checker is a simple, accurate, and cost effective way to measure high ranges of ammonia in fresh water.
Designed as a more accurate alternative to chemical test kits, the HI-733 provides quick, accurate results in four easy steps.
The HI-733 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.
CheckerHC is supplied with reagents for 10 tests.
