Service, Repair & Spare Parts

The Series DO4000 sensor, in conjunction with the MicroChem®2[S4] Series 4000 transmitter is a simple and reliable Dissolved Oxygen measuring system. The immersion probes are designed for direct insertion into tanks, open channels and basins. A flow-through cell version allows measurements in continuous non-pressurized sampling systems.

The sensor cartridge is manufactured using a process that permanently encapsulates a solution of sodium chloride (common salt) behind a permanently bonded PTFE membrane. Since the electrolyte solution is a solution of common salt, there are no environmental or health & safety risks associated with the sensor. Unlike other systems that require membrane changes and electrolyte replacement. The DO4000 sensor is inexpensive and simple to install.

Dissolved oxygen passing through the membrane causes the electrodes to generate a current that is proportional to the concentration of dissolved oxygen in the sample. The sensor includes a thermistor to compensate the measurement for temperature variations.

The probe’s rugged design assures mechanical protection for the measuring cell and provides the IP68 ingress protection. The probe may be inserted to depths of 10 FT (3 m). When the measured sample contains suspended particles that may deposit on the membrane or bio fouling which can lower the probe sensitivity, a jet cleaning option is available. During the cleaning sequence the transmitter output is held at the last measurement.
