The HI 733 Checker®HC 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. 

1.) Step One - Add 1ml of sample and 9ml of reagent “B” to the included cuvette
2.) Step Two - Insert sample into the Checker and zero it out 
3.) Step Three - Remove sample and add reagent “A”
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 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.

Fluoride is one of the very few chemicals that have been shown to cause significant effects in people through drinking-water. Fluoride has beneficial effects on teeth at low concentrations in drinking-water, but excessive exposure to fluoride in drinking-water, or in combination with exposure to fluoride from other sources, can give rise to a number of adverse effects.
