Condition: For Parts or Not Working
This MSA Model 20 Portable Combustible Gas Indicator is being sold as-is for parts or repair. We tested the meter operation and the calibrator, which functioned; however, we were unable to test the sensor, so its condition is unknown. The unit is not guaranteed functional as a complete working gas detector. The green metal case shows significant wear throughout — paint is heavily chipped and worn on all sides and the bottom, with bare metal exposed in multiple areas. The leather shoulder and carry strap is intact and present. The battery compartment door and spring battery clips are included. The instruction and calibration index card is present inside the lid. Please view our photo set and contact us if you have any questions.
