DS Oxygen Probe - Laboratory Grade Oxygen Probe

Supplier: Ceramic Oxide Fabricators (Australia)

The type DS oxygen probe is suitable for measurement of oxygen concentration over the range from pure oxygen down to 10-24 atmospheres at temperatures from 700°C to 1650°C

Price Guide: POA

The type DS probe consists of a SIRO2 oxygen sensor with an internal thermocouple, with a small industrial thermocouple head with all electrical and reference air connections. All wiring and electrodes are platinum, for the best possible corrosion resistance and refractoriness.

A ceramic sheath over the sensor is an option. A sheath is useful to protect the platinum wire if the probe is frequently removed and re-installed. The standard sheath material is limited to 1300°C (2400°F). High temperature sheaths are available on special order – please enquire.

Read the probe measurements with the type AIC hand-held digital meter, for a quick and simple indication.

Probes include a 4-pin Cannon type cord plug, ready for connection to any suitable 4-conductor cable.

We recommend a shielded umbilical cable for greater accuracy over long cable runs. We supply a braided four wire cable with a Cannon plug at each end. We use R-type thermocouple compensation wire in the cable. A reference air hose is also fitted in the cable.

The DS oxygen probe is scientific laboratory use, a gas-tight seal is often required at the insertion point. The DS probe has a vaccuum sealed, stainless steel extension tube over the first 50 mm of the sensor. This extension tube can easily be fitted into an O-ring seal.
