Hanna HI-707 Nitrite Low Range Handheld Colorimeter Checker HC

The Hanna (HI707) Nitrite Checker measures exceptionally low levels of Nitrite and bridges the gap between simple chemical test kits and professional instrumentation. With 1 part per billion (ppb) resolution it provides accurate digital readout of Nitrite levels in water.With its fantastic ability to measure exceptionally low levels of nitrite, the Hanna Nitrite Checker is an boon for salt water aquarists.Nitrites are an intermediate form of nitrogen produced when ammonia is converted into nitrate during the nitrogen cycle. As organic matter decays, it produces ammonia; the highly toxic ammonia is converted into nitrite by bacteria; and the nitrite is then converted into nitrate by another bacteria.Nitrite is dangerous to aquatic life if it is allowed to build up, causing tissue damage that can lead to illness and death. By detecting even minute levels of nitrite, the Hanna Nitrite Checker can help aquarists to take action at the earliest possible moment and eliminate unnecessary suffering among the fish. Accurate and easy to use, a bright tactile little tester that’s attractive to hold and easy to use.The Hanna HI707 Nitrite Checker Features:Accuracy ±10 ppb1 part per billion resolutionLarge easy to read LCD displayAuto shut-off ensures longer battery lifeFully portable, fitting easily into palm and pocketThe HI707 Checker for Nitrite comes complete with:2 sample cuvettes1 black cuvette capStarter pack of 6 reagents1 x 1.5V AAA batteryFull working instructionsThe Hanna HI764 Nitrite Checker Specification:Range0 to 600 ppbResolution1 ppbPrecision±4% of reading ±10 ppb @ 25ºCLight SourceLED @ 525 nmLight DetectorSilicon photocellEnvironment0 to 50°C (32 to 122°F); RH max 95% non-condensingBattery Type(1) 1.5V AAAAuto-offAfter 3 minutes of non-useDimensions81.5 x 61 x 37.5 mmWeight64 gMethodAdaptation of EPA Diazotization method 354.1 The Hanna HI707 Nitrite Checker for Low Range (LR) Nitrite Analysis, Accurately measure low levels of nitrite !
