Chemical Oxygen Demand Portable Photometer – HI97106
HI97106 is a waterproof portable photometer that benefits from Hanna’s years of experience as a manufacturer of analytical instruments. It is a compact and versatile device designed to accurately determine chemical oxygen demand. The photometer has an advanced optical system that uses a Light Emitting Diode and a narrow band interference filter for accurate, repeatable readings. The optical system is sealed from outside dust, dirt, and water.
The meter uses an exclusive positive-locking system to ensure that the vials are placed into the holder in the same position every time. With the CAL Check™ functionality, users are able to validate the performance of the instrument at any time. Hanna Instruments CAL Check cuvettes are certified against NIST‑traceable reference instrument(s). The built-in tutorial mode guides users step by step through the measurement process. The tutorial mode includes all steps required for sample preparation, the required reagents, and quantities.
Suitable for bench measurements, the photometer features :
– Sophisticated optical system
– Meter validation using certified CAL Check cuvettes
– Tutorial mode guides the user step‑by‑step
– Auto logging
– Waterproof IP67 floating case
