The
HI96771
is an auto diagnostic portable microprocessor meter that benefits from
Hanna Instruments’ years of experience as a manufacturer of analytical instruments. It has an
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
TM
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 Instruments ready‑made, NIST traceable standards to verify the performance of
the instrument and recalibrate if necessary.
The instrument is splash proof and the LED and filter units are protected from dust or dirt by a
transparent cup. This makes the instruments fulfill field applications. Display messages aid the user
in routine operations. The meter has an auto‑shut off feature that will turn off the instrument after
10 minutes of non use in measurement mode or after 1 hour if left in calibration mode.
The meter uses an exclusive positive‑locking system to ensure that the cuvette is in the same
position every time it is placed into the measurement cell. It is designed to fit a cuvette with a
larger neck making it easier to add both sample and reagents. The cuvette is made from special
optical glass to obtain best results.
The
HI96771
meter measures the free chlorine (Cl
2
) content in water samples in the 0 to 5.00 mg/L
(ppm) range and chlorine ultra high range in the 0 to 500 mg/L (ppm) range. The methods are an
adaptation of Standard Methods for the Examination of Water and Wastewater, 20
th
edition, 4500‑Cl.
The reagent is in
powder form and is supplied in packets. The amount of reagent is precisely dosed
to ensure the maximum repeatability.
