Specification Sheet

Iodine is sometimes used as a disinfectant for
swimming pools, spas and potable water. It has also
found use as a disinfectant in the poultry industry.
The rapid determination of iodine is required for
adequate control of this bactericide.
The HANNA Checker®HC’s bridge the gap between
simple chemical test kits and professional
instrumentation. Chemical test kits are not very
accurate and only give 5 to 1
0 points resolution while
professional instrumentation can cost hundreds of
dollars and can be time consuming to calibrate and
maintain. The HANNA HI 718 and Checker®HC is
accurate and affordable.
The HI 718 Checker®HC portable handheld
colorimeter features a resolution of 0.1 ppm and
accuracy of ±0.1 ppm ±5% of reading. This Checker®
HC uses a modification of the DPD method used for
residual chlorine.
The c
onto
ured style of this Checker®HC fits in your
palm and pocket perfectly and the large LCD is easy to
read. The auto shut-off feature assures the battery
life will not be drained if you forget to turn it off.
The HI 718 is extremely simple to use. First, zero the
instrument with your water sample. Next, add the
reagent. Last, place the vial into the instrument,
press the button and read the results. It
’s
t
hat easy.
