    HI 707

    Checker®HC Handheld Colorimeter – Nitrite Low Range


    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. 

    FEATURES/BENEFITS: 
    * Small palm-sized design
    * Accurate from ±20 ppb ± 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

    PRIMARY APPLICATIONS: 
    * Water Quality
