innoSens 450-RSDigital Dissolved Oxygen Sensors

Applications：

Sewage/wastewater treatment, surface water, aquaculture

Features

The innoSens 450-RS digital dissolved oxygen sensor has a built-in temperature probe and uses optical technology for measurement: a diode shoots blue light directly towards a fluorescent layer, which reacts with red light (fluorescence) when sensitive substances are irradiated, and the time of the red light emission is related to the concentration of oxygen. This innovative method ensures reliable, accurate and drift-free measurements.

No maintenance required
No consumables, calibration and maintenance are required. The fluorescent cap needs to be replaced only once in 1 - 2 years.
