For the safe use of this equipment
CAUTION
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
measured gas may damage the sensor.
• The detector (especially at the tip) becomes very hot. Be sure to handle it with gloves.
WARNING
The product is very heavy. Handle it with care. Be sure not to accidentally drop it. Handle safely
to avoid injury.

Some process gas is dangerous to people. When removing this equipment from the process line
for maintenance or other reasons, protect yourself from potential poisoning by using a protective
mask or ventilating the area well.
