Specification

The HI 96781 meter measures the free and total chlorine ( Cl2) content in water samples in the 0.00 to 5.00 mg/ L ( ppm) range.
It has the advanced optical system based on a special tungsten lamp and a narrow band interference filter that allows for the 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 validation function, you are able to validate performance of the 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 water resistant and the lamp and filter units are protected from dust or dirt by a transparent cup. This makes the instrument ideal for 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 reagents are in powder form and supplied in packets. The amount of reagent is precisely dosed to ensure the maximum repeatability.
