Single Parameter Check – Ammonia
- Handheld Colorimeters
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Small size, big convenience
- Ideal for Water quality
The HI700, HI715, and HI733 Checker®HC’s are simple, accurate, and cost effective ways to measure ranges of ammonia in fresh water. The all new HI700 Checker®HC Ammonia LR for fresh water can be used to replace the usage of of HI3824 or HI38049 fresh water test kits.
Designed as a more accurate alternative to chemical test kits, the HI700, HI715, and the HI733* provides quick, accurate results.
Step One – Add a sample to the included cuvette(s).
Step Two – Insert sample into the Checker and press the button to zero.
Step Three – Remove sample and add reagents as the manual states.
Step Four – Reinsert sample, press and hold the button for 3 seconds to start reaction timer. reading will be taken automatically and the results displayed.
* HI733 uses a different procedure
All three models use 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.
