Hanna Instruments High Range Nitrate Checker HI782

The Hanna Instruments High Range Nitrate Chequer HI782 is a device that measures nitrate levels in saltwater aquariums precisely.

Nitrate marks the final stage in the nitrogen cycle. Excessive nitrate concentrations in saltwater aquariums can foster the growth of unwanted organisms such as algae and dinoflagellates. With the HI782, accurately measuring nitrate levels from 0.0 to 75.0 ppm (as NO3) in your saltwater aquarium is simple, accurate, and cost-effective.

The HI782 Nitrate Chequer HC utilises the Zinc Reduction Method to measure nitrate concentration colorimetrically. With just four easy steps, the HI782 provides quick and precise results:

1. “Zero” the Chequer HC as required.
2. Add reagents to your water sample.
3. Place the vial into your Chequer HC.
4. Press the button and read the results.
