Zirconia O2 Sensors
Probe Series - Short Housing

The Probe Range of zirconium dioxide oxygen sensors are available in three lengths. Suitable for aggressive and polluted applications such as boiler exhausts. Longer probes are an ideal solution for thicker walled, insulated flue pipes.

FEATURES
* Zirconium dioxide (ZrO2) sensing elements
* Long life, non-depleting technology
* Integral heating element
* High accuracy
* Requires an external interface board to operate

BENEFITS
* No reference gas required
* No need for temperature stabilisation
* Compact enclosure
