Product Description

O2I-Flex Oxygen Sensor Interface Board Description
The O2I-Flex Oxygen Sensor Interface Electronics provides the electronics necessary to power and control SST’s range of zirconium dioxide oxygen sensors.

The O2I-Flex oxygen sensor interface electronics can be user configured to output measuring ranges of 0-25% O₂ and 0-100% O₂. The entire measurement range is linear in both cases and offers three output options 0-10V, 4-20mA and RS232 comms interface.

The O2I-Flex can be calibrated in fresh air (20.7% O₂) or in any other known O₂ concentration by either an automatic or manual external trigger or via an on-board push button switch. The electronics offer power and sensor operating LEDs and removable polarised screw terminals for easy wiring.

The adaptive software filtering provides a fast sensor response coupled with a stable oxygen output.
