4P-90 4P-90C PM143-000 Combustible Gas Sensor For Catalytic Combustion

Product Description:

4P-90 4P-90C PM143-000 Combustible Gas sensor For Catalytic Combustion



Features:

The table below shows the variation in response of a 4P-

90 CiTipeL on exposure to a range of gases and vapours

at the same %LEL concentration. The figures are

experimentally derived and expressed relative to the

methane signal (=100).

Note: The results are intended for guidance only. For the

most accurate measurements an instrument should

be calibrated using the gas under investigation.
