Next Generation Photoionization Detector Measures Benzene at 50 Parts Per Billion

Jul 25 2008

RAE Systems Inc. (USA) have introduced the UltraRae 3000, the next generation photoionization detector (PID) for compound-specific gas monitoring. It was shown for the first time at the recent American Industrial Hygiene Conference in Minneapolis.
The UltraRae 3000 makes use of proprietary pre-filter tubes to measure specific gases such as benzene and butadiene. The UltraRae 3000 is wirelessly enabled, making it compatible with the industry-standard AreaRae network for remote data measurement and collection. The UltraRae 3000 uses the same high-performance detection technology as the ppbRae 3000, with the ability to measure toxic compounds below 50 parts per billion (ppb). The UltraRae3000 is intended for use in many industrial environments including confined space entry, prescreening
during refinery and plant maintenance, hazardous material response, marine spill response, and refinery down-stream monitoring.
“The UltraRae 3000 supports two detection modes,” said Thomas Negre, director of instrumentation products for Rae Systems. “The instrument can be used for 60-second snapshot assessments as well as longer short-term exposure limit (STEL) surveys.”
The UltraRae 3000 is extremely versatile, as it also measures total VOCs in two wide ranges: 0 to 1000 ppm with a resolution of 0.05 ppm or 1,000 to 10,000 ppm with a resolution of 1 ppm. The monitor also has integrated correction factors for more than 200 compounds. The UltraRae 3000 can be used to measure either benzene or butadiene with the appropriate RaeSep™ compound-specific filtering tube. It also employs Rae Systems’ standard two-button user interface for easy learning and operation, and has intrinsic safety certificates for use in hazardous
atmospheres for the Americas (UL/CSA) and Europe (ATEX).
