Dissolved Oxygen is typically measured in many processes, some examples are: wastewater treatment plants, fish breeding, fermenters, haemodialysis.
CLR manufactures highly reliable polarographic sensors for the measure of oxygen, 2 electrodes, membrane type.
Oxygen in air is measured in rooms where there may be a dangerous lack of this gas.
These oxygen measuring cells are available for laboratory use and for industrial applications, with many different installation accessories (e.g. the immersion probes, the float for variable level tanks...).  These cells are also used  to measure oxygen in air.

The measuring instruments for the a.m. parameters are available for industrial applications and in the portable version.

We can supply process instrument suitable for panel mounting and for in-field installation (IP65 protection degree):
among  these, the uP transmitter-indicator-controller  is available in two versions: the complete version uP and the light version uPLT.

Main features for both units:
. local indication of measured parameter and process temperature,
. temperature compensation of the measure through dedicated algorithms,
. automatic calibration procedure (in air)
. isolated 4-20 mA output (not available in the uPLT version),
. 4 programmable digital control outputs (2 for the uPLT version),
. self diagnostic and sensor diagnostic functionality,
. capability to drive the cleaning sequence for the sensor.
. freely programmable linearization curves

In the same family the PID controller, suitable for panel mounting and for in-field installation (IP65 protection degree), has the same features of the uP transmitter, and additionally allows PID process control either through contact control output or analog control output.
 
The line now includes a transmitter-controller with RS485 serial interface and MODBUS RTU communication protocol, Mod.TX  and the Transmitter Indicator Controller c/w local keyboard and diplay Mod.TX-HMI.
Main features for these units:
. display indication of both analysis and temperature values (TX-HMI)
. automatic thermo compensation of the measure via software through specific algorithms
. automatic calibration procedure (in air)
. RS 485 serial interface with MODBUS RTU communication protocol
. 2 analog output 420 mA for measure and tempertaure
. 2 digital outputs from relay, programmable
. 2 digital inputs, programmable
. remote calibration capability
. isolated 24 Vdc power supply; 24 Vac power supply
. suitable for rear panel mounting (DIN bar)  and for outdoor installation (IP 65 protection degree)
. freely programmable linearization curves


Also, we have  developed a  Dissolved Oxygen analyser for oenology and wineries
