This document provides the instruction manual for HI 96715C Ammonia Medium Range ISM 2 Ion Selective Meter by Hanna Instruments Inc., including specifications, precision and accuracy, principle of operation, functional description, errors and warnings, measurement and calibration procedures, etc.
The HI 96715C is an auto-diagnostic portable microprocessor meter designed to measure ammonia nitrogen (NH3-N) content in water samples ranging from 0.00 to 9.99 mg/L. It utilizes an advanced optical system based on a special tungsten lamp and a narrow band interference filter to ensure accurate and repeatable readings. The instrument features a powerful CAL CHECK validation function and is splash waterproof for field applications.
The manual covers the preliminary examination of the instrument, general description, specifications, and the principle of operation based on the Lambert-Beer Law. It details the functional description of the keypad and display, operating modes including measurement, calibration, and GLP modes, as well as procedures for startup, measurement, validation, and calibration. Additionally, it provides information on battery management, accessories, and warranty.
