To replace a malfunctioning CO2 external temperature sensor (Catalog Number/ Order Code OK_400103-U) on an Orbisphere ProBrix+ follow the steps below:
- Disconnect the gray cable from the back of the CO2 sensor.
- Unscrew the temperature sensor, and pull the cable straight out from the temperature sensor. It is possible to remove the old sensor and install the new one without removal of the flow cell. (Note an O-ring on the old sensor should be removed and installed on the new sensor since new sensors don't come with the o-ring.)
