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. If the primary need is to detect a specific combustible
gas other than methane, please contact Honeywell Analytics to discuss an alternative
product.

Please use caution when using the BW Clip4 around Methanol and/or Ethanol. The
BW Clip4 CO sensor may become inhibited by prolonged exposure to concentrations of
Methanol and/or Ethanol thus causing the unit to alarm. This condition can last up to
12 hours before the CO sensor recovers to normal levels.
