GENERAL DESCRIPTION
9V
SLIDE
OFF
The HI 95771 is an auto diagnostic portable microprocessor meter that benefits from Hanna’s
years of experience as a manufacturer of analytical instruments. It has the advanced optical
system based on a special tungsten lamp and a narrow band interference filter that allows most
accurate and repeatable readings. All instruments are factory calibrated and the electronic and
optical design minimizes the need of frequent calibration.
With the powerful CAL CHECK™ validation function you are able to validate good performance of
your instrument at any time. The validation procedure is extremely user friendly. Just use the
exclusive Hanna ready-made, Nist traceable standards to verify the performance of the instrument
and recalibrate if necessary.
All instruments are splash proof and the lamp and filter units are protected from dust or dirt by
a transparent cup. This makes the instruments fulfill field applications. Display codes aid the
user in routine operation. The meter has an auto-shut off feature that will turn off the instrument
after 10 minutes of non use or after 1 hour if left in the calibration mode.
The meter uses an exclusive positive-locking system to ensure that the cuvet is in the same
position every time it is placed into the measurement cell. It is designed to fit a cuvet with a
larger neck making it easier to add both sample and reagents. The cuvet is made from special
optical glass to obtain best results.
The HI 95771 is a dual range meter that can measure the chlorine (Cl
) content in water
2
samples in the 0 to 5.00 mg/L (ppm) range and in the 0 to 500 mg/L (ppm) range. The
methods are an adaptation of Standard Methods for the Examination of Water and
th
Wastewater, 20
The reagents are in
edition, 4500-Cl.
powder form and are supplied in packets. The amount of reagent is precisely
dosed to ensure the maximum repeatability.

FACTORY CALIBRATION RESET
It is possible to restore factory calibration:
• Enter the calibration mode by holding CAL CHECK
for three seconds.
• Hold ZERO/SET for 10 seconds. The display
will show for 2 seconds “F.CAL” and "771" or
“701” appears. The factory calibration is
automatically restored and the instrument is
ready for measurement by displaying "771" or
“701” on the LCD depending to which
parameter code has been selected.
BATTERY REPLACEMENT
Battery replacement must only take place in a
non-hazardous area.
Simply slide off the battery cover on the back of
the meter. Detach the battery from the terminals
and attach a fresh 9V battery while paying attention
to the correct polarity. Insert the battery and
replace the cover.
