This manual provides you with the necessary information for the correct use of the instrument
The HI 96700C is an auto-diagnostic portable microprocessor meter designed to measure ammonia-nitrogen (NH3-N) content in water samples within the range of 0.00 to 3.00 mg/L. It utilizes a special tungsten lamp and narrow band interference filter for accurate photometric chemical analysis based on the Nessler method.
The instrument features an advanced optical system, splash waterproof design, and auto-shut off functionality. Users can perform measurements, calibration, and validation using the CAL CHECK function to ensure good performance. The manual covers preliminary examination, startup procedures, measurement steps, calibration methods, and battery management.

The meter measures ammonia-nitrogen content in water samples in the 0.00 to 3.00 mg/L (ppm) range.
The instrument turns off after 10 minutes of non-use in measurement mode or after 1 hour if left in calibration mode.
The method is an adaptation of the ASTM Manual of Water and Environmental Technology, method D1426-92 Nessler method.
