HI97715C – Portable Photometer for Ammonia: Field Performance and Analytical Reliability
The HI97715C photometer from Hanna Instruments is specially designed to meet the requirements of ammonia nitrogen analysis in natural, industrial or waste water. Ammonia, in dissolved form in water, is a critical indicator of pollution and can be extremely toxic to aquatic environments in excessive concentrations. The HI97715C provides accurate and reproducible measurements of this indicator using proven optical technology, while ensuring ease of use in the field.
Based on the Nessler method, in accordance with ASTM D1426-92, the HI97715C uses a 420 nm LED light source and a silicon photometric cell to ensure remarkable accuracy. The instrument has a resolution of 0.01 mg/L and a measurement range from 0.10 to 10.00 mg/L of NH₃-N, with an accuracy of ±0.05 mg/L or ±5% of the reading at 25°C. This performance makes it ideal for environmental professionals or field operators who need a compact, reliable and efficient device.
The device comes with a sturdy carrying case containing all the accessories needed to get started right away: cuvettes, CAL CHECK certified calibration solutions, cleaning cloths, scissors and batteries. Thanks to the CAL CHECK function, the user can check and adjust the accuracy of the instrument at any time using certified standards. The GLP function allows calibration data to be recorded to ensure complete traceability in accordance with good laboratory practice.
The HI97715C is equipped with a multi-level illuminated display with an intuitive virtual keypad interface, making it easy to use even in low light conditions. Its IP67-rated housing ensures optimal protection against water and dust, and its floating design prevents loss if accidentally dropped in a wet environment. With over 800 measurements on battery power without backlighting, this device is a reliable long-term ally.
All these features make the HI97715C the ideal choice for professionals looking for a robust, accurate and easy-to-use portable photometer for ammonia analysis in aqueous media.
