The
HI 96770
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 Light Emitting Diode (LED) 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.
The instrument is splash waterproof 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 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 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 96770
meter measures the molybdate reactive silica (SiO
2
) content in water samples in the 0
to 200 mg/L (ppm) range. The method is an adaption of the USEPA METHOD 370.1 for drinking,
surface and saline waters, domestic and industrial wastes and Standard Method 4500-SiO
2
C.
The reagents are in
powder form and are supplied in packets. The amount of reagent is precisely dosed
to ensure the maximum repeatability.
