Description
The Hanna Instruments HI97733 is an advanced, high-range portable photometer specifically engineered for the precise quantitative determination of ammonia (NH4+) in freshwater and wastewater applications. Utilizing an adaptation of the ASTM Manual of Water and Environmental Technology D1426-92 Nessler method, this instrument delivers laboratory-grade accuracy in a rugged, field-ready form factor. The Original Engineering of the optical system features a reference detector and narrow band interference filter, eliminating errors caused by light source drift and ambient temperature fluctuations.

System Architecture & Integration:
The HI97733 integrates Hanna’s exclusive CAL Check validation and calibration system, allowing operators to verify instrument performance using NIST-traceable standards. The internal optical architecture utilizes a beam splitter to direct light to a reference detector, ensuring consistent intensity and compensating for LED degradation over time. The IP67-rated housing ensures Technical Compatibility with harsh industrial environments, floating if accidentally dropped in water. The cuvette holder is designed with a positioning ridge to ensure consistent path length and optical alignment for every measurement.
Industrial Application & Value:
In municipal wastewater treatment plants and industrial effluent discharge facilities, high concentrations of ammonia pose severe toxicity risks to aquatic ecosystems and indicate process failures in nitrification stages. The HI97733 allows plant operators to conduct rapid, on-site high-range ammonia testing without the need for complex laboratory titration setups. By providing immediate, accurate data, facilities can adjust aeration rates and chemical dosing in real-time, preventing regulatory compliance violations. Standardized reagents and an optimized supply chain ensure minimal Lead Time for consumables, maintaining continuous operational readiness.
