They are commonly added to drinking water as a corrosion inhibitor. The instantaneous analysis of orthophosphates by colorimetric determination provides rapid results using a standard analysis technique. The Hanna HI774, HI713, HI7134 and HI717 Checker®HC bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give some points resolution, while professional instrumentation can cost hundreds of dollars and can be time-consuming to calibrate and maintain. These Checker HC's are accurate and aordable. The HI774 Checker HC is a simple, accurate, and cost eective way to measure ultra low range phosphates in seawater. HI774 features a resolution of 0.01 ppm and ±0.02 ppm ±5% of reading accuracy. The HI774 Checker HC uses an adaptation of the Ascorbic Acid method. The HI713 and HI7134 Checker HC portable handheld colorimeters features a resolution of 0.01 ppm and ±0.04 ppm ±4% of reading accuracy. The HI713 Checker HC uses an adaptation of the Ascorbic Acid method. The HI717 Checker HC portable handheld colorimeter features a resolution of 0.1 ppm and ±1.0 ppm ±5% of reading accuracy. The HI717 Checker HC uses an adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition, Amino Acid method.
