The HI 96715  is an auto diagnostic portable microprocessor meter that benefits from Hanna’s

years of experience as a manufacturer of analytical instruments. It has the 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.

 

The instrument is splash waterproof and the LED and filter units are protected from dust or dirt

by a transparent cup. This makes the instruments fulfill 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 cuvette is in the same

position every time it is placed into the measurement cell. It is designed to fit a cuvette with a

larger neck making it easier to add both sample and reagents. The cuvette is made from special optical glass to obtain best results.

 

The HI 96715 meter measures the ammonia nitrogen (NH3-N) content in water samples in the 0.00 to 9.99 mg/L (ppm) range. The method is an adaptation from ASTM Manual of Water and Environmental Technology, D1426-93, Nessler Method. The reagents are liquid form and are supplied in bottles. The amount of reagent is precisely dosed to ensure the maximum repeatability
