Dissolved Oxygen Analyzer for Galvanic Probe

Controller to carry out the measurement of Dissolved Oxygen for Autoclean galvanic probe
Suitable for in sewage units, hydroponic systems, with continuous readings on digital indicatorsl.
2 min/max relays.
Range from 0.0 to 199.9% Air saturation.

SKU: OD7685.010 Category:

Dissolved Oxygen Analyzer for Galvanic Probe autoclean. The controller can be connected to a galvanic cell with 1mil/2 mil/5mil membranes.
It provides manual and automatic temperature compensation. The instruments provides also the temperature reading.


This Dissolved Oxygen analyzer for galvanic probe give both a valid, low cost measurement and requlation system for large or small industrial and ecological plants, sewage units, hydroponic systems and they can be used as 0/20mA (optional 4/20mA) visualized transmitter for field applications.


Connections are made by mean of two extractable terminal blocks on the rear side of the instrument, which allow easy cables connection and easy maintenance of the instrument.


The panel mounting instrument’s enclosure is designed according to the DIN 43700 standards and it consist of a plastic case with metallic front panel coated with polycarbonate membrane, to ensure the maximum anticorrosion characteristics.
