It is important to minimize the amount of time a Teledyne Trace Oxygen sensor is exposed to air during the installation process. The quicker the sensor can be installed into the unit, the faster your sensor will recover to low oxygen measurement levels.

CAUTION: Do not touch the sensing surface of the cell. It is covered with a delicate Teflon membrane that can leak when punctured. The sensor must be replaced if the membrane is damaged.

Check O-ring in the base of the cell holder before installing a new cell. Replace it if worn or damaged.
