The essential portable photometer for detecting low concentrations of phosphates
In the current context of sustainable water resource management, accurate detection of nutrients such as phosphates is crucial. The HI97713 from Hanna Instruments is a complete solution for measuring these concentrations in aquatic environments, wastewater, and agricultural systems. Thanks to its advanced optical system, this device guarantees excellent measurement stability and is perfectly suited for mobile use.
Featuring innovative LED technology combined with a reference detector and a focusing lens, the HI97713 minimises errors due to variations in the light source or cuvette defects. This design ensures reproducible results, even in difficult field conditions. Unlike older generations of photometers, the use of highly efficient LEDs produces stable light without generating heat, promoting long-term electronic stability.
The user interface is designed for simplicity: a backlit display, integrated educational animations and a step-by-step guide for measurements make the instrument accessible even to non-specialist users. The CAL Check™ function, based on NIST traceable standards, allows the accuracy of the instrument to be validated at any time, ensuring compliance with traceability and quality control requirements.
Completely waterproof (IP67 rated), the HI97713 floats if dropped in water, making it a reassuring choice for field use. It automatically stores up to 50 results, displays the battery status, automatically turns off when not in use, and stores the last calibration data to meet GLP (Good Laboratory Practice) requirements.
The measurement is based on an adaptation of the reliable and proven ascorbic acid colorimetric method, widely used in environmental analysis. In summary, the HI97713 is a comprehensive and robust precision tool for monitoring phosphates in a variety of environments.
