GLP Features
The HI 96724 meter measures the free and total chlorine content in water samples in the 0.00 to 5.00
mg/L (ppm) range. The method is an adaptation of the USEPA Method 330.5 for wastewater, and
Standard Method 4500-CL G for drinking water. The HI 96724 incorporates an advanced optical
system based on a special tungsten lamp and a narrow band interference filter that allows the most
accurate and repeatable readings. The instrument is 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
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.
The instrument is 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 liquid form and are supplied in dropper bottles. The amount of reagent is
precisely dosed to ensure the maximum repeatability.
