Hanna Trace Total Chlorine Waterproof Photometer
Total chlorine is given by the sum of free chlorine plus combined chlorine, where free chlorine combines with nitrogen to produce chloramines. Chloramines is harmful to aquatic life and damages water treatment plants that use membranes for water purification (e.g. reverse osmosis). Chloramines concentration in water depends on pH, temperature, the initial ratio of chlorine and amines, chlorine demand and total time of exposure.

Chloramines is harmful to aquatic life and damages water treatment plants that use membranes for water purification (e.g. reverse osmosis). Chloramines concentration in water depends on pH, temperature, the initial ratio of chlorine and amines, chlorine demand and total time of exposure.
Both forms of chlorine (free and combined) can exist at the same time, though they need to be measured separately. HI 96761 is an auto-diagnostic portable photometer for accurately measuring trace total chlorine for ion-exchange membranes and resins. The advanced optical system employs a specialized tungsten lamp and a narrow band interference filter, assuring accurate readings between 0.000 to 0.500 mg/L.
The Hanna Trace Total Chlorine Waterproof Photometer 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 96761 utilizes an adaptation of the Standard Methods, 20th Edition, 4500-Cl G. The reaction between chlorine and DPD causes a pink tint in the sample.
