Photoionization detector measures benzene at 50 parts per billion
UltraRAE 3000 photoionization detector offers compound-specific gas monitoring. Makes use of proprietary prefilter tubes to measure specific gases such as benzene and butadiene. Wirelessly enabled detector is compatible with industry-standard AreaRAE network for remote data measurement and collection, according to manufacturer. Uses same high-performance detection technology as ppbRAE 3000, with ability to measure toxic compounds below 50 parts per billion. Also measures total VOCs in two wide ranges: 0 to 1,000 parts per million (ppm) with a resolution of 0.05 ppm; or 1,000 to 10,000 ppm with a resolution of 1 ppm. RAE Systems Inc., San Jose, Calif.
