Specifications HI782 (HR) Range 0.0 to 75.0 ppm (as NO² – ) Resolution 0.1 ppm Accuracy ±2.0 ppm ±5% of reading @ 25 °C (77 °F) Light Source Light Emitting Diode @ 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. Environment 0 to 50 °C (32 to 122 °F); max. 95% RH non-condensing Battery Type 1.5V AAA Alkaline Auto-off After 10 minutes of non-use Dimensions 86.0 x 61.0 x 37.5 mm (3.4 x 2.4 x 1.5”) Weight 64 g (2.3 oz) Interferences Nitrite Ordering Information HI782 Checker HC is supplied with sample cuvette and cap (2 pcs.), Marine Nitrate High Range reagent starter kit (reagents for 10 tests), 3 mL Pasteur pipette (1 pc.), 1.5V AAA Alkaline battery (1 pc.), and instruction manual Reagent Set HI782-25 Reagents for 25 Marine Nitrate High Range tests Calibration Set HI782-11 Marine Nitrate HR certified standard kit See page10.166 for Checker HC accessories HI782 Marine Nitrate High Range Handheld Colorimeter • Ideal for aquariums and marine biology • Easier to use and more accurate than chemical test kits • Small size, big convenience Nitrate is a by-product of the Nitrogen cycle. Excessive amounts of Nitrates in a marine aquarium can promote the growth of undesirable organisms including algae and dinoagellates and increase the risk of livestock illness or death. The HI782 Marine Nitrate HR (High Range) Checker HC is a handheld colorimeter that uses the Beer-Lambert principle to determine the concentration of nitrate colorimetrically. The HI782 is designed speci¡cally to measure high levels of nitrate in a saltwater aquarium. The 0.0 to 75.0 ppm range is ideal for coral/ ¡sh or ¡sh-only aquarium maintenance. | www.hannainst.com 10 10.158 Photometers Checker®HC
