HI97733 Ammonia Photometer – The professional solution for accurate and reliable ammonia analysis
The HI97733 ammonia photometer is the result of decades of expertise in the design of high-precision analytical instruments. Designed specifically for measuring ammonia in water, this portable device features a state-of-the-art optical system combining a light-emitting diode (LED) and a narrow-band filter to ensure accurate, reproducible measurements with a low margin of error.
Using an adaptation of the Nessler method (method D1426), the HI97733 can detect ammonia at high concentrations of up to 100.0 mg/L. This performance makes it an essential tool for environmental analysis, drinking water or wastewater monitoring, and in the aquaculture sector. Its ability to deliver accurate results in the field also makes it valuable in in situ measurement campaigns.
The device is distinguished by its robustness and ease of use. Its IP67-rated, floating housing is designed to withstand the most demanding conditions, ensuring its longevity even in humid or dusty environments. The optical system is hermetically sealed against external interference, and the instrument incorporates a focusing lens that limits the impact of cuvette imperfections on the measurement.
One of the major advantages of the HI97733 is its exclusive CAL Check™ function, which allows users to quickly validate the accuracy of their measurements using NIST-certified calibration cuvettes. This regular validation ensures the continued reliability of the device, while offering the option of user calibration if required.
For ease of use, a tutorial mode guides the user step-by-step through all stages of the measurement, from sample preparation to reagent selection and handling instructions. The device can also store up to 50 measurements, facilitating data tracking and compliance with good laboratory practices.
Compact, intuitive and reliable, the HI97733 photometer meets the requirements of professionals who need an accurate, portable diagnostic tool that is suitable for a variety of environments.
