    A perfect low cost solution for hydrogen detection in battery rooms, or for LEL or PPM level detection of a variety of flammable or solvent vapors in general industry.

    The Model PS 2 is a multipurpose gas monitor utilizing a MOS (metal oxide sensor) for long lasting and low maintenance detection at the LEL or PPM levels of many gases or vapors. The PS 2 has two alarm levels for increasing gas or vapor levels, at the PPM level for detection of many solvent vapors, or for LEL level detection of flammable vapors. 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 alarming 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) is also built in which activates in a gas alarm condition.

    The standard PS 2 is supplied with the gas sensor located on the end of a 30 foot cable (other cable distances are also available). Each unit is powered by 115 VAC standard or 24 VDC as standard (48 VDC versions optional), and the AC version comes complete with a 6′ power cord.

    Detectable Gases

    The PS 2 uses a Metal Oxide Semiconductor (MOS) type sensor for the detection of gases and vapors. This MOS sensor is known for its very long life and truly low maintenance requirements. The PS 2 and its MOS sensor effectively respond to a wide variety of hydrocarbons and other gases or vapors. Alarms can be set for OSHA established TLV levels for many gases or solvent vapors, and at LEL levels for flammable vapor warnings.

    Since the PS 2 sensor is a general hydrocarbon sensor, it is not specific for any particular gas. This instrument will perform best if used in an area where the only gas or vapor present, besides fresh air, is the gas or vapor that you wish to detect. If used in an area contaminated with many different gases or vapors, false alarms may occur. Please carefully evaluate the application and the area to ensure that no interfering gases are present.

    The PS 2 is an effective solution for solvent vapor monitoring around degreasers or other processes, hydrogen monitoring in battery rooms, natural gas detection in basements around landfills, and many others. Please consult the factory for practical alarm points for your application.
