Msa Safety 0019-7075 Combustible Gas Leak Detector

Product Description

The MSA SAFETY 0019-7075 is a handheld combustible gas leak detector designed for trade professionals who need fast, reliable leak identification in the field. It detects all combustible gases with no calibration required and delivers a response time of 1 second. Two sensitivity modes are available: low sensitivity at 50 ppm methane and high sensitivity at 20 ppm methane. The sensor is located in the probe tip for maximum sensitivity and easy replacement. A long, flexible probe neck allows access to hard-to-reach areas such as valve bodies, regulators, and buried fittings. Visual and audible indicators confirm leak presence immediately.

This detector is suited for residential, commercial, and industrial applications including gas pipeline surveying, valve and regulator inspection, and gas meter inspection. The automatic background adjustment feature allows technicians to work in areas where trace levels of target gas are already present without false-positive interference. It operates on four AA alkaline batteries with a typical run time of 14 hours, making it practical for full-day field use. The unit is compact and designed for single-handed operation.

Key Features

• Dual sensitivity modes: 50 ppm methane (low) and 20 ppm methane (high) for flexible field use
• 1-second response time with sensor located at probe tip for fast, pinpoint detection
• Automatic background adjustment for detecting leaks in gas-present environments
• Long, flexible probe neck for access to confined or hard-to-reach leak points
• UL 913 certified for hazardous locations: Class 1, Division 1, Groups A, B, C, and D
• Expected sensor service life of 5 years with a 2-year warranty including the sensor

Compatibility

Designed for detecting combustible gases in residential, commercial, and industrial gas systems including pipeline, meter, regulator, and valve applications.

Installation Notes

This instrument is installed and operated by licensed gas technicians and HVAC professionals. Before conducting leak surveys near active equipment, follow site-specific lockout and hazardous-area entry procedures as applicable. Allow approximately 1 minute of warm-up time before placing the unit into service. Do not expose the sensor to liquid water or condensing humidity, as the rated operating range is 10 to 70 percent RH non-condensing.
