The HI97106 Portable Photometer by Hanna Instruments is a professional device designed for precise determination of chemical oxygen demand (COD) in water samples using the Closed Reflux Method. It features an advanced optical system with LEDs, interference filters, and high-sensitivity silicon photodetectors, delivering stable, repeatable, and highly accurate results. The instrument’s housing is rated IP67, making it completely dust-tight and resistant to temporary immersion in water, allowing reliable operation even in challenging field conditions.

The HI97106 offers a user-friendly interface with a large backlit LCD display, supports automatic calibration and self-diagnostics to minimize operational errors. It can store up to 50 measurement results with date and time stamps, ensuring proper data tracking. Compact and lightweight, this photometer is easy to transport and operate in the field. The HI97106 is ideal for environmental monitoring, wastewater and drinking water analysis, industrial process control, municipal water utilities, and research laboratories.
