Clarkson HI96771C
Chlorine Waterproof Photometer Kit Ultra-High Range Cal Check
Hanna Instruments HI 96771C
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.
