The Air check Methyl Bromide Monitor is a compact, tractive continuous gas monitoring system designed to monitor in hazardous areas. The system uses our proprietary renewable electrochemical sensor cell combined with a long life pyrolizer to provide tremely sensitive and specific Methyl Bromide monitoring. Unlike traditional LEL solid-state detectors, the Air check pyrolizer technology is tremely sensitive and capable of detecting parts-per-million concentrations of Methyl Bromide at TLV levels without being affected by humidity or other environmental conditions.

The heart of the monitoring system is a long life pyrolizer designed to convert Methyl Bromide to an electrochemically active gas detected on PureAire’s renewable sensor cell. And the low cost renewable sensor cell offers the lowest annual preventative maintenance materials at about $75 per year for electrolyte replacement. The Air check electronics, pyrolizer, sample pump and sensor cell are housed in a Nema 4 weather proof enclosure.

The instrument’s “smart” circuitry continuously monitors sensor cell status and sampling system performance. Continuous sensor cell operation is transmitted via 4-20mA signal to PureAire controllers, PLC’s or remote alarm systems. Should a system error occur, the Air check outputs a specific mA signal to remote alarm/control systems to immediately alert control room personnel.
