Model / part: SR-W-MP75C (SRWMP75C)
SR-W-MP75C MICROpeL combustible-gas (LEL) replacement sensor. This is a sensing component, not a complete gas detector.
The compatible MicroClip instrument indicates 0-100% LEL; that is an instrument measurement range, not a standalone accuracy specification for the loose sensor.
Check the detector and full part number
Manufacturer reference documents list SR-W-MP75C for GasAlertMicroClip XT, XL and X3, and GasAlertMax XT II. Its Max XT II parts list separately identifies SR-W-MP75 as the unfiltered version; do not drop the C suffix when matching the replacement.
Confirm the detector model and old sensor label. Follow the detector service instructions for replacement, calibration and bump testing before use.
