Replacement combustible (LEL) sensor without heavy duty silicone filter for the GasAlertMicro 5 series of BW gas detectors. Detectors are equipped on a standard basis with SR-W04 combustible sensors. This sensor includes a heavy duty silicone filter that make it ideal for use in environments that have known sources of silicone or vapors containing silicon. The SR-W04 silicone filter equipped sensor should not be used when monitoring diesel, kerosene, jet fuel or other heavy hydrocarbon vapors with flashpoint temperatures above 38°C (100°F).
Note: This sensor includes a 2 year warranty from BW Technologies.
