Honeywell Analytics recommends performing a calibration at least once every 180 days (6 months). • The combustible gas sensor is initially calibrated to 50% LEL methane.

No response Acetylene No response For any gases not listed, please contact Honeywell Analytics to find the best solution for your application. The BW Clip4 LEL sensor is optimized to see methane. While the unit can detect and respond to the other combustible gases listed in the above table, the accuracy of the readings may be in-consistent.
