Nitrite LR Checker HC HI 707
The HI 707 Checker®HC is a simple, accurate, and cost effective way to measure low ranges of nitrite. Designed as a more accurate alternative to chemical test kits, the HI 707 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 707 uses an adaptation of EPA diazotization method 354.1. The reaction between nitrite and the reagent causes a pink tint in the sample.
