HI 723 Checker®HC Handheld Colorimeter

Chromium VI High Range

 

  • Easier to use and more accurate than chemical test kits

    Diphenylcarbohydrazide method
    Accuracy ±5 ppb ±5% of reading
    1 ppb (µg/L) resolution
    Large, easy to read digits
    Auto shut off

  • Dedicated to a single parameter

    Designed to work with HANNA’s powder reagents
    Uses 10 mL glass cuvettes

  • Small size, big convenience

    Weighing a mere 64 g (2.25 oz.), the Checker®HC easily fits
    into the palm of your hand or pocket
    Use for quick and accurate on the spot analysis
    Single button operation: zero and measure
    Operated by a single AAA battery

  • Ideal for Water Quality

There are two natural forms of ionic chromium, the hexavalent ion, Cr (VI) and the trivalent Cr (III). Cr (III) is much less toxic than Cr (VI) and seldom found in potable waters. Cr (VI), however, is toxic to humans and is found in water. Even though the toxic effects from Cr (VI) in drinking water are not well documented, it is a suspected carcinogen. The maximum permissible level or Cr (VI) allowed to be released into the waterways is 50 ppb. Its level in drinking water is normally much lower and a lever higher than 3 ppb is suggestive of industrial pollution.

By monitoring this parameter with the HANNA HI 723 Checker®HC, serious health and safety risks can be avoided.

The HI 723 Checker®HC is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagent, shake vigurosly for 10 seconds. Last, place the vial into the Checker®HC, press the operational button for about 3 seconds and the display will show the countdown prior to the measurement or, alternatively, wait for 6 minutes and press operational button. When the timer ends the meter will perform the reading. The Checker®HC displays concentration in ppb of chromium VI. It’s that easy.
