O2S-T3 / O2S-FR-T3 Miniature Zirconium Dioxide Oxygen Sensor

Zirconia O2 Sensors
Miniature Series

The Miniature Zirconium Dioxide Oxygen Sensors can be PCB mounted and are used when measuring ambient gas with the complete sensor immersed in the atmosphere which is to be measured.

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
• PCB mountable
