14.9 Installation and calibration
The detector will be installed with the sensor cell pointing downwards
The detector should be calibrated with the gas to be measured. With respect to combustible
gases only, and in the event it is impossible to calibrate with the targeted gas, see tables on
pages 76 and further for recommended calibration gas and cross gas interference.
14.10 Marking
The OLCT80 is available with a ATEX marking of gas and vapor groups IIB and IIC.
For the detection of group IIC gases (Hydrogen, acetylene, carbon disulphide and
ethyl nitrate) only the IIC marking is available.
