Checker®HC Handheld Colorimeter – Ammonia Low Range for Fresh Water
The all new HI 700 Checker Ammonia LR for fresh water can be used in place of HI 3824 or HI 38049 fresh water test kits. The Checker®HC 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.
1.) Step One – Add a sample to the included cuvette(s)
2.) Step Two – Insert sample into the Checker and zero it out
3.) Step Three – Remove sample and add reagent (A & B – 4 drops of each)
4.) Step Four – Reinsert sample and click the button to measure your results or…
– Press and hold the button for 3 seconds for a time reaction reading
The 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.
