About Hanna Instruments High Range Nitrate Checker HI782

Nitrate is the final step in the Nitrogen cycle. Excessive amounts of nitrates in saltwater aquariums facilitate the growth of undesirable organisms such as algae and dinoflagellates. The HI782 is a simple, accurate, and cost-effective way to measure nitrate from 0.0 to 75.0 ppm (as NO3–) in your saltwater aquarium. The HI782 Nitrate Checker HC uses the Zinc Reduction method to measure the concentration of nitrate colorimetrically. The HI782 provides quick, accurate results in four easy steps: "Zero" the Checker HC as required in the specific procedure Add reagent to your water sample Place the vial into your Checker HC Press the button and read the results Features: For use with salt water samples. More accurate than chemical tests kits. Dedicated to a single parameter. Small size, big convenience. No errors with a digital readout. Ideal for aquariums and marine biology applications. Specifications: Range: 0.0 to 75.0 ppm (as NO3-) Resolution: 0.1 ppm Accuracy at 25 degrees C: ±2.0 ppm ±5% of reading at 25 degrees C (77 degrees F) Light Souce: LED at 525 nm Light Detector: silicon photocell Method: Zinc reduction method. The reaction between nitrate and the reagent causes a pink tint in the sample. This checker has been developed to work with seawater samples.
