HI 95771
is a photometer developed to check chlorine dosing in disinfection processes
|
|
with high concentrations of chlorine. Thanks to the extended range
from 0 to 500 ppm,
|
|
it is ideal for the food industry, such as in fruit and vegetable
washing. HI 95771 also offers
|
|
an
additional range (0.00 to 5.00 ppm) for accurate
measurements at lower values, to help
|
|
control the chlorine level before discharging the treated water.
Finally, instrument validation
|
|
is possible at any time with
Cal CheckTM standard cuvets.
|
|
With HANNA’s exclusive CAL CHECKTM validation
function users are able to verify the
|
|
performance of the instrument at any time. Taking just a few short
steps, the validation
|
|
procedure is extremely user
friendly and ensures that the meter is properly calibrated.
|
|
Just use
the exclusive HANNA ready-made, NiST traceable standards
to verify the performance
|
|
of the instrument and recalibrate if necessary. All instruments are
factory calibrated and the
|
|
electronic and optional design minimizes the need for frequent
calibration.
