Effective June 25, 2008, the Department of Pesticide Regulation of the California EPA has added a real time remote sensor monitor for the detection of methyl bromide by PureAire Monitoring Systems, in addition to colorimetric detector tubes. The PureAire Air Check Advantage Continuous Methyl Bromide Monitor can now be used to monitor enclosed areas, including greenhouse soil fumigation and commodity fumigation.

The PureAire Air Check Advantage Methyl Bromide Monitor is capable of low 0.3 parts-per-million (PPM) detection and includes a local digital display, 4-20 mA analog output, user-settable high and low concentration alarm relays, and a failsafe system fault relay. Designed for monitoring fumigation chamber clearing and storage areas, it’s ideal for providing worker protection at orchards, growers, international airports, and seaports where commodities are fumigated before shipping.

The heart of the Air check Advantage is a highly reliable and substance-specific detection system, which converts methyl bromide into a gas more easily and selectively detected by a renewable electrochemical sensor. Annual maintenance costs are estimated at approximately $75/year and can save an average orchard up to $16,000 per year in colorimetric tubes.
