Checker®HC Handheld Colorimeter – Nitrite HR
The HI 708 Checker®HC is a simple, accurate, and cost effective way to measure high ranges of nitrite. Designed as a more accurate alternative to chemical test kits, the HI 708 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 708 uses an adaptation of the Ferrous Sulfate method. The reaction between nitrite and the reagent causes a greenish/brown tint in the sample.
* Small palm-sized design
* Accurate from ±3 ppm ±5% of reading
* Dedicated to a single parameter
* Uses a single AAA battery
* Auto Power Off after 10 minutes in inactivity
* Built-in timer for timed reaction readings
