Orthophosphates are found in natural and wastewaters. 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 717 Checker®HC bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give only a few resolution points, while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The HANNA HI 717 Checker®HC is accurate and affordable.
The HI 717 Checker®HC is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagents. Last, place the vial into the Checker®HC, press the button and read the results. It’s that easy.
Order Information: HI 717 Checker®HC is supplied with sample cuvettes with caps (2), reagents for 20 tests, battery and instructions.
