Datasheet

Chlorine is the most common water disinfectant. The
monitoring of chlorine is crucial in applications such
as swimming pools and spas, fruit and vegetable
sanitation, disinfection and drinking water. By
monitoring this crucial parameter, serious health and
safety risks can be avoided.
The
HANNA HI 711 and HI 701 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 10 points
resolution while professional instrumentation can
cost hundreds of dollars and can be time consuming
to calibrate and maintain. The
HANNA HI 711 and
HI 701 Checker®HC’s are accurate and affordable.
These Checker®HC portable handheld colorimeters
feature a resolution of 0.01 ppm (250 points for free
chlorine, 350 for total chlorine) and ±3% of reading
±0.03 ppm (mg/L) accuracy. They also use an EPA
approved DPD method.
The contoured style of these Checker®HC’s fit 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 711 and HI 701 Checker®HC’s are extremely
simple to use. First, zero the instrument with your
water sample. Next, add the reagent. Last, Place the
vial into the Checker®HC, press the button and read
the results. It’s that easy.
