Product Description

The Hanna Instruments HI 736 Checker HC Handheld Colorimeter for Phosphorus is portable meter for measuring phosphate levels.

The HI 736 bridges the gap between less accurate chemical test kits, and expensive professional test instrumentation. The HI 736 operates using a silicon photocell light detector, and has an accuracy of + or - 5% using an adaptation of Standard Method Ascorbic Acid. To use, simply 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 736 operates in temperatures from 0 to 50 degrees C (32 to 122 degrees F)/RH max 95% with a range of 0 to 200 ppb with precision + or - 5% ppb at 25 degrees C. The device operates on one 1.5V AAA battery, with an auto-off function that shuts off the device after three minutes of non-use. Dimensions are 81.5 x 61 x 37.5 mm (3.2 x 2.4 x 1.5”) and weighs 64 g (2.25 oz.).

Orthophosphates are present in water from the natural weathering of mineral deposits, agricultural runoff, untreated sewage, animal waste, fertilizers and as a corrosion inhibitor in drinking water. Phosphate photometers are used by researchers, manufacturers, and individuals to monitor phosphate levels in the environment, and in the home.

Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries in 32 countries.
