Clarkson HI96771
Chlorine, Ultra-High Range Photometer with 525 nm filter and Cal Check
Hanna Instruments HI 96771
Description:
Responding to the user's requirements for analyzing high concentrations of chlorine, HANNA® offers
HI 96771, a portable auto-diagnostic photometer which measures free chlorine from 0 to 5.00 and 0
to 500 mg/L range. The advanced optical system employs a specialized tungsten lamp and a narrow
band interference filter, assuring accurate readings. This instrument is equipped with Cal Check®
validation function and standards to validate good performance at any time. Taking just a few short
steps, the validation procedure is user-friendly and ensures that the meter is properly calibrated
wherever you go. Hanna photometers use the exclusive ready-made, NiST traceable standards to
verify the performance of the instrument and recalibrate if necessary. Cuvets are constructed from
specialized optical glass to ensure the best and most consistent results. The positive locking system
ensures that the cuvet is in the same position every time it is placed into the measuring cell. Our
sample cell is designed to fit a cuvet with a wide neck to make it easier to add both sample and
reagents. All instruments are factory calibrated and the electronic and optical design minimizes the
need for frequent calibration. Ideal for field applications, these meters are splash proof and the lamp
and filter units are protected from dust or dirt by a transparent barrier. Display messages aid the user
during routine operation. The auto-off feature will disengage the meter after 10 minutes of non-use in
measuring mode or 1 hour while in calibration mode. HI 96771 utilizes an adaptation of Standard
Methods for the Examination of Water and Wastewater, 20th Edition, 4500-Cl. The reaction between
free chlorine and the reagents causes a yellow tint (UHR) or pink tint (LR) in the sample.

CHECK™ standards and reagents sold separately.
