Orthophosphates are found in natural and wastewaters. 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 HI713 Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give only some points resolution, while professional instrumentation can cost hundreds of dollars and can be time-consuming to calibrate and maintain. The Hanna HI713 and HI717 Checker®'s are accurate and affordable.
The HI713 Checker® portable handheld colorimeter features a resolution of 0.01 ppm (250 points) and ±0.04 ppm (mg/L) ±4% of reading accuracy. The HI713 Checker® uses an adaptation of Standard Method 4500-P E, Ascorbic Acid method.
The HI713 Checker® is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagents. Last, place the vial into the Checker®, press the button and read the results. It’s that easy.
