* Response of the RAE Systems LEL sensor to a range of gases at the same LEL, expressed as percent of
methane response (=100). These figures are for guidance only and are rounded to the nearest 5%. For the
most accurate measurements, the instrument should be calibrated with the gas under investigation. See
RAE Systems Technical Note TN-156 for more details and other compounds.
Caution:
Refer to RAE Systems Technical Note TN-144 for LEL sensor poisoning.
