The
HI96701
is an auto diagnostic portable microprocessor meter that benefits from
Hanna Instruments’ 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
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.
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 messages 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 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
HI96701
meter measures the free chlorine (Cl
2
) content in water samples in the
0.00 to 5.00 mg/L (ppm) range. The method is an adaptation of the EPA DPD Method 330.5 for
wastewater, and Standard Method 4500-Cl G for drinking water.
The reagent is in powder form and is supplied in packets. The amount of reagent is precisely dosed
to ensure the maximum repeatability.
