49840 Explosimeter Combustible Gas Indicator for Oxygen-acetylene Atmospheres, Complete with Carrying Straps, Less Sampling Line by MSA
Detects and measures concentrations of combustible gases or vapors in the air. This instrument can be used in the immediate environment or, with sampling lines and probes, it can draw samples from remote areas and is housed in a cast aluminum case.
- Quickly detects and measures concentrations of combustible vapors and gases in air
- Suitable for remote sampling
- Durable cast aluminium case
- Four models tailored to specific applications
Principles of Operation:
A single control knob turns the instrument on and sets the detection filament voltage. Gas concentrations up to 100 percent of LEL are measured directly on the meter. Concentrations in the explosive range are indicated by full-scale deflection of the meter pointer.
