HI 715
Checker®HC Handheld Colorimeter - Ammonia Medium Range

The HI 715 Checker®HC is a simple, accurate, and cost effective way to measure medium ranges of ammonia in fresh water. Designed as a more accurate alternative to chemical test kits, the HI 715 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
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 715 uses an adaptation of the ASTM Manual of water and Environmental Technology D1426-93, Nessler Method. The reaction between ammonia and reagents causes a yellow tint in the sample.
