MSA Portable Alarm Model 361 Hydrogen Sulfide Oxygen
The MSA 361 is a portable, confined-space indicator and alarm for monitoring oxygen (0-25%), hydrogen sulfide (0-50ppm) and combustible gas (0-100% LEL). An internal sampling pump allows the sample to be drawn to the instrument from a remote location prior to human entry.
This machine can operate for 8-10 hours on a full charge (battery alarm was going off when powered on, so battery is most likely dead). The large display is easy to read and has a momentary switch for back lighting. It also has low battery alarm and visual alarm indicators.
This portable alarm is an ex-military piece and was rated A. It powers on, but we did no further testing; this piece is being listed here AS_IS. Includes all pieces shown. This equipment was originally in a hard shell case, but the packing was severely deteriorated so we removed the equipment and cleaned it off.
This item powers on, but is otherwise untested and being listed here AS_IS.
