Dissolved O2 probe
Digital dissolved oxygen sensor
The T-O2 sensor works with TriBox and TriBox Mini transmitters.
The measurement of dissolved oxygen according to the luminance method is carried out without prior calibration. No interference with HS, reducing or oxidizing substances. This technology allows reliable and precise measurements with a membrane replacement only every two years.
Digital communication ensures safe and trouble-free transmission of the signal from the sensor to the controller.
Available with fixed cable of 2 or 10 meters. Possible cable extensions, 0.3 m, 2 m, 10 m and 25 m.
Measurement principle
The T-O2 probe uses the principle of luminescence to measure the dissolved oxygen concentration in water. The dissolved oxygen penetrates into a phosphor whose radiation by light excitation is measured. The dissolved O2 molecules absorb this emitted light, the difference in intensity between the measurement and the reference point is proportional to the oxygen concentration of the water.
