Free and Total Chlorine Photometer
HI 96711 is an auto diagnostic portable microprocessor meter. It has an advanced optical system based on a special tungsten lamp and a narrow band interference filter that allows 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 CAL CHECK™ validation function you are able to validate good performance of your 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 splash proof and the lamp and filter units are protected from dust or dirt by a transparent cup. This makes the instruments fulfill field applications. Display codes aid the user in routine operation. Acoustic signals are used to make the instrument more user-friendly. The meter has an auto shut-off feature that will turn off the instrument after 10 minutes of non-use 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 HI 96711 meter measures the free and total chlorine (Cl2) 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 reagents are in powder form and are supplied in packets. The amount of reagent is precisely dosed to ensure the maximum repeatability.
