Hanna Instruments HI713 Phosphate Low Range Checker® HC
The HI 713 Checker HC Handheld Photometer for Phosphate is a portable tester for measuring orthophosphates in natural, waste, and drinking waters.
The HI 713 bridges the gap between less accurate chemical test kits, and expensive professional test instrumentation. The HI 713 features a resolution of 0.01 ppm (250 points) and 4% + or - 0.04 accuracy of reading. To use, zero the instrument with your water sample, then add the reagent. Place the vial into the checker, press the button and read the results within seconds.
The HI 713 operates in temperatures from 0 to 50 degrees C (32 to 122 degrees F)/RH max 95% with a range of 0.00 to 2.50 ppm (mg/L) with precision + or - 0.04 ppm (mg/L) + or - 4% of reading at 25 degrees C. The device operates on one 1.5V AAA battery, with an auto-off function that shuts off the device after two minutes of non-use. Dimensions are 81.5 x 61 x 37.5 mm (3.2 x 2.4 x 1.5€Â) and weight is 64 g (2.25 oz.).
Orthophosphates are present in water from the natural weathering of mineral deposits, agricultural runoff, untreated sewage, fertilizers and, as an addition to drinking water, to inhibit corrosion. Phosphate photometers are used by researchers, manufacturers, and individuals to measure phosphate levels in the environment, and in the home.
