The
HI 95734
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 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 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 95734
meter measures the free and total chlorine (Cl
2
) content in water samples in the
0.00 to 10.00 mg/L (ppm) range. The method is an adaption of the USEPA METHOD 330.5 for
wastewater, and Standard Method 4500-Cl G for drinking water.
The reagents are in
powder and liquid form and are supplied in packets and bottles. The amount of
reagent is precisely dosed to ensure the maximum repeatability.

Recommendations for Users
Before using these products, make sure that they are entirely suitable for your specific application and for the
environment in which they are used.
Operation of these instruments may cause unacceptable interferences to other electronic equipments, this requiring the
operator to take all necessary steps to correct interferences.
Any variation introduced by the user to the supplied equipment may degrade the instruments' EMC performance.
To avoid damages or burns, do not put the instrument in microwave ovens. For yours and the instrument safety do not
use or store the instrument in hazardous environments.
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.
