RAE Systems to Exhibit Gas Detection Products for Industrial Hygienists at AIHce


Targeted Line of Specialty and Wireless Solutions for Industrial Safety

San Jose, Calif. - May 26, 2009 - RAE Systems Inc. (NYSE 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 personal, portable, wireless and fixed gas detection and industrial hygiene monitoring solutions at booth 1221 at the American Industrial Hygienists Conference and Exposition (AIHce) being held at the Metro Toronto Convention Center in Toronto, Canada, on June 1-3, 2009.

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 safety challenges for industrial safety is the effective, accurate sensing of unseen threats in real time," said Thomas Negre, director of instrumentation products for RAE Systems. "Our instruments and calibration stations 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 play 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 (photoionization detection) and wireless technology, RAE Systems will feature single-gas and multi-gas products, as well as calibration stations for a wide range of industrial applications.

Wireless System Products featured for industrial applications include:

o AreaRAE(TM) Steel, the 5-sensor, wireless toxic gas and radiation detection system with three new sensor options: hydrogen chloride (HCl), hydrogen fluoride (HF) and high-range carbon monoxide (CO).
o RAELink3, the wireless modem and repeater for AreaRAE networks.

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 compact, one- to four-sensor gas detector, now available in both diffusion and internally pumped models, ideal for combustibles, oxygen, hydrogen sulfide and carbon monoxide.
o ToxiRAE(TM) 3 single-gas detectors for carbon monoxide or hydrogen sulfide.
o AutoRAE Lite automated calibration solution for either the single-gas ToxiRAE 3 detector or the 1- to 4-gas QRAE II confined space entry monitor.

Next-Generation Photoionization Detectors, including:

o MiniRAE 3000, the parts-per-million total volatile organic compound monitor with wireless capability and intrinsic safety certification
o MiniRAE Lite, the VOC monitor for outdoor environmental applications.
o ppbRAE 3000, the parts-per-billion VOC monitor with wireless capability and intrinsic safety certification.
o UltraRAE 3000, the wireless, intrinsically safe, compound specific VOC monitor for benzene or butadiene.

To see a demonstration of these products at the AIHce, please visit the RAE Systems booth, #1221, at the Metro Toronto Convention Center in Toronto, Canada, on June 1-3, 2009.
