GENERAL DESCRIPTION
The HI 96711 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
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 ready-made, NIST traceable standards to verify the performance of the
instrument and recalibrate if necessary.
All instruments are splash waterproof 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 HI 96711 meter measures the free and total chlorine (Cl
0.00 to 5.00 mg/L (ppm) range. The method is an adaptation of the USEPA Method 330.5 for
wastewater, and Standard Method 4500-Cl G for drinking water.
The reagents are in powder form and supplied in packets. The amount of reagent is precisely
dosed to ensure the maximum repeatability.
