Calibration Gas: Type and Concentration

PIRECL supports three selections for calibration gas type; Ethane, Methane and “same as measured”.

Typically the calibration gas type is the same as the measured gas, however, in some installations it may be

preferred to use a single type of calibration gas to calibrate a number of hydrocarbon detectors even though they

are not all characterized to monitor the same gas in normal operation.

PIRECL supports the use of either Methane or Ethane as a calibration gas regardless of the “Gas Type” selected

for the detector. Of course, the “measured gas” can also be selected as the calibration gas type.

Once the calibration gas type is set, the concentration must be set. The default value of 50% LFL can be

changed between 20% LFL and 100% LFL to match the gas being used.
