Did we mention that its Salt Water Compatible? WORKS GREAT IN SALT WATER ENVIRONMENTS!ACCURATE AND AFFORDABLE NITRITE ULR MEASUREMENT. 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. Highly toxic ammonia is converted into nitrite by bacteria, and the nitrite is converted into nitrate by another bacteria. Nitrite is dangerous to aquatic life if it builds up, causing tissue damage that can lead to illness and death.The HANNA HI 764 Checker®HC bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The HANNA HI 764 Checker®HC is accurate and affordable. This Checker®HC features an accuracy of ±4% of reading and uses an adaptation of EPA Diazotization method. The contoured style of this Checker®HC fits in your palm and pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off. The HI 764 Checker®HC is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagent. Last, Place the vial into the HI 764 Checker®HC, press the button and read the results. It’s that easy.Over the past 30 years, HANNA has never failed to design fresh and innovative products. The new Checker®HC’s are no exception.
