RAE Systems to Introduce New Gas Detection Products for Industrial Hygienists at AIHce


Expanding Line of Specialty and Wireless Solutions for Industrial Gas Detection

San Jose, Calif. - May 27, 2008- RAE Systems Inc. (AMEX: RAE),a leader in delivering innovative sensor solutions to serve industrial, energy, environmental and government safety markets worldwide, will exhibit the company's leading gas detection and industrial hygiene monitoring solutions and introduce next-generation photoionization (PID) based instruments and wireless gas detection solutions at booth #615 at the American Industrial Hygienists Conference and Exposition (AIHce) being held at the Minneapolis Convention Center in Minneapolis, Minnesota, on June 2-4, 2008.

The conference is jointly hosted by the American Industrial Hygiene Association (AIHA) and the American Conference of Governmental Industrial Hygienists (ACGIH®). Thousands of industrial hygienists and other Office of Environmental Health and Safety (OEHS) professionals are expected to attend.

"One of the biggest challenges in the industrial safety environment is the effective, accurate sensing of unseen threats in real time," said Thomas Negre, director of instrumentation products for RAE Systems. "Our next-generation products for the measurement of toxic and flammable volatile organic compounds (VOCs) put a new level of information in the hand of industrial safety officers. Industrial hygienists strive to keep workers, their families, and their communities healthy and safe. They provide a critical role in making sure that federal, state, and local laws and regulations are followed in the work environment."

In addition to demonstrating the latest in PID (photo-ionization detection) and wireless technology, RAE Systems will feature single- and multi-gas products for a wide range of industrial applications.

Wireless System Products featured for industrial applications include:

o AreaRAE(TM) Steel, the 5-sensor, wireless detection system with three new sensor options: Hydrogen Chloride (HCl), Hydrogen Fluoride (HF) and high-range Carbon Monoxide (CO).

o LifeShirt(TM), a durable, lightweight chest strap with sensors that can be integrated with the AreaRAE to monitor the vital signs of high-risk industrial workers and first responders.

Confined space entry gas detection products include:

o MultiRAE(TM) Plus, the original handheld, multi-gas monitor with photoionization detection (PID).

o QRAE(TM) II, the compact, one- to four-sensor gas detector in both diffusion and now available with an internal pump, ideal for combustibles, oxygen, hydrogen sulfide, sulfur dioxide and carbon monoxide.

o ToxiRAE(TM) 3, the single-gas detectors for carbon monoxide or hydrogen sulfide.

o AutoRAE Lite, single-gas detector calibration solution.

To see a demonstration of any of these products at the AIHce, please visit the RAE Systems booth #615 at the Minneapolis Convention Center on June 2-4, 2008.
