Safety instructions

5.1

Designated use

The oxygen sensor is suitable for continuous measurement of dissolved oxygen in water.
The specific suitability depends on the sensor design:
• COS22/COS22-*1 (standard, measuring range 0.01 to 60 mg/l)
– Measuring, monitoring and regulating the oxygen content in fermenters
– Monitoring the oxygen content in biotechnology facilities
• COS22/COS22-*3 (trace measurement, measuring range 0.001 to 10 mg/l, preferred operational
range 0.001 to 2 mg/l), also suitable for high CO
– Monitoring inertization equipment in the food industry
– Monitoring the residual oxygen content in carbonated fluids of the beverage industry
– Trace measurement in industrial applications such as inertizations
– Monitoring the residual oxygen content in boiler feedwater
– Monitoring, measuring and regulating the oxygen content in chemical processes
NOTICE
Molecular hydrogen
Hydrogen causes sensitivity in other substances and leads to false low readings or, at the worst, total
failure of the sensor.
► Do not use the sensor in media containing hydrogen.
5.2

Installation, commissioning and operation

• The device/measuring system may only be installed, connected, operated and maintained by trained
technical personnel (e.g. certified electrician). The technical personnel must strictly adhere to the
Operating Instructions, prevailing standards, legal regulations and certificates (depending on
application).
• If the Brief Operating Instructions do not provide sufficient information, you must read the Operating
Instructions. There, you can find detailed information on the device.
• The operator may only perform modifications and repairs of the device/measuring system that are
explicitly permitted in the Operating Instructions.
• Do not operate damaged products and secure them against unintentional
commissioning. Mark the damaged product as being defective.
• If faults can not be rectified, the products must be taken out of service and secured against
unintentional commissioning.
