Note: Values in bold type are confirmed with RAE Systems by Honeywell instruments. Others, shown in
italic, are calculated from diffusion models.
* 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.
