Orthophosphates are found in natural
waters 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 and HI717 Checker®HC
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®HC's are
accurate and a'ordable.
The HI713 Checker®HC portable handheld
colorimeter features a resolution of 0.01 ppm
and ±0.04 ppm ±4% of reading accuracy.
The HI713 Checker®HC uses an adaptation of
the Ascorbic Acid method.
