16 Monitoring tcGas Remembraning the tcGas Transducer

1Unscrew the protection cap from the transducer and hook the O-ring remover under both O-rings to remove them.

2Remove both of the clear plastic membranes using your fingers.

3Clean the transducer head, including the groove and rim, with absorbent paper to remove all old electrolyte (old electrolyte causes incorrect values) and apply approximately two drops of electrolyte solution to the transducer head.

4Press the transducer head downwards into an unused membrane replacer until the replacer retracts as far as it can and you hear a click. Discard used replacer.

5Remove any surplus electrolyte solution on the outside of the membranes with a soft tissue.

6Make sure that the new membranes are secured by two O-rings on the transducer. If any air bubbles are visible under the membranes, repeat this procedure - air bubbles will cause incorrect readings.

7After 24 hours you can calibrate the transducer. You must remembrane all new and dried out transducers twice before calibration.

New/Dried Out Transducers

Remembrane all new or dried out transducers twice before using. After the first remembraning, unplug the transducer from the module and leave it for 24 hours with the cap on. Remembrane again before calibrating.

Storing tcGas Transducers

If you need to store a sensor for more than 24 hours, protect it for up to 28 days by putting two drops of electrolyte solution into the cap. Screw the cap on the sensor. Remembrane if it dries out or after 28 days.
