Used specifically for measuring LELs or PPM, the PS2 monitor is an easy, standalone, single-point solution. The PS2 uses both visual and audible alarms and has two alarm levels for different levels of vapors or gasses.

The body of the PS2 is a plastic enclosure with a wall mount. A 30’ cable with a sensor located on the end comes standard with the PS2, although variable cable lengths are available.
