ACCURATE AND AFFORDABLE CHLORINE MEASUREMENT
Orthophosphates are found in natural and waste waters. They are commonly added to drinking water as a corrosion inhibitor. The instantaneous analysis of orthophosphate by colorimetric determination provides rapid results using a standard analysis technique. The HANNA HI 755 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 755 Checker HC is accurate and affordable. The HI 755 Checker HC portable handheld colorimeter features a resolution of 0.1 ppm (250 points) and 10 percent + or - 0.1 accuracy of reading. 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 755 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 755 Checker HC, press the button and read the results. It is that easy.
