NOTE
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 water dropping directly on the probe (sensor) of the detector when installing it.
• Check the calibration gas piping before introducing the calibration gas to ensure that there
is no leakage of the gas. If there is any leakage of the gas, the moisture drawn from the
sample gas may damage the sensor.
• The detector (especially at the tip) becomes very hot. Be sure to handle it with gloves.
