Air check Advantage Methyl Bromide Fumigation Monitor

The PureAire Air check Advantage is a compact, extractive gas monitoring system that's ideal for continuously and remotely monitoring fumigation chambers and fruit storage areas where access may be limited or undesirable. Featuring a special pyrolizer and sample pump, this accurate methyl bromide gas monitor has been tested to provide ultra low 0.3ppm and lower detection of methyl bromide levels in the workplace. PureAire's continuous monitor eliminates the need to subject an employee into fumigation chambers to manually take colorimetric grab samples to determine if an area is safe to enter.

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 Advantage outputs a signal to remote alarm/control systems to immediately alert control room personnel.

The heart of the system is a smart renewable sensor cell linked to a compact pyrolizer. Sample is drawn through the pyrolizer where Methyl bromide is thermally decomposed and converted into another gas that is more easily detected electrochemically. Unlike competitive Methyl bromide detectors and colorimetric tubes which have interferences to humidity, temperature and moisture, the Air check sensor and electronics are unaffected by changes in environment. This stability provides true sub TLV measurement of methyl bromide in product storage areas without the need for conversion tables.
