PS2 Stand Alone LEL Monitor

A perfect low cost solution for hydrogen detection in battery rooms, or for LEL level detection of a variety of flammable or solvent vapours in general industry. The Model PS 2 is a multipurpose gas monitor utilising a MOS (metal oxide sensor) for long lasting and low maintenance detection of LEL levels of many gases or vapours. The PS 2 has two alarm levels for increasing gas or vapour levels. Inquire at the factory for your specific requirement. Each alarm level activates a 12 amp relay inside the unit, and terminals are provided for wiring the relay to activate an external alarm device or some other device such as a ventilation fan. This stand alone unit is housed in a durable plastic enclosure with flanges provided for wall mounting and is designed with easy access wiring hubs on the bottom of the unit. The front of the PS 2 contains three lights; Pilot, Alarm 1, and Alarm 2. An internal audible alarm (85 db) activates in a gas alarm condition, and alarm relays are activated. The standard PS 2 is supplied with the gas sensor located on the end of a 30 foot cable (other cable lengths are also available). Power options include 24 VDC as standard, with 115 VAC or 48 VDC versions available, and the AC version comes complete with a 6′ power cord. For use in non hazardous locations only.
