CAUTION
Sensor Handling
The cell (sensor) at the tip of the detector is made of ceramic (zirconia element). Do not drop the detector or
subject it to pressure stress.
Do NOT allow the sensor (probe tip) to make contact with anything when installing the detector.
Avoid any direct water drop on the probe (sensor) of the detector when installing it.
Check the verification gas piping before introducing the gas to ensure there is no leakage of the gas. If
there is any leakage of the gas, the moisture drawn from the measuring gas can damage the sensor.
The detector (especially at the tip) becomes very hot. Be sure to handle it with gloves.
Oxyfire-LT may be heavy. Handle it with care. Do not drop it. Handle safely to avoid injury.
