RAE Systems to Introduces Fixed and Wireless Toxic and Flammable Gas Detection Solutions for Liquid Terminal Operators


San Jose, Calif.- June 2, 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 new fixed and wireless flammable and toxic gas detection solutions at booth #821 of the 29th Annual International Liquid Terminal Operating Conference & Trade Show (ILTA) being held June 9-10, 2009, at the Hilton Americas-Houston & George R. Brown Convention Center in Houston, Texas.

"This conference and tradeshow gives RAE Systems the opportunity to showcase our new offerings in rapidly deployable, intrinsically safe, wireless solutions for toxic gases and flammability, as well as our drop-in fixed-system detector heads that integrate with traditional 4-20mA hard-wired systems," said Jesper Jensen, RAE Systems' fixed products manager. "Our mesh radio-based solutions offer a new paradigm in industrial monitoring."

RAE Systems will feature the following fixed and wireless toxic and flammable gas detection systems:

o The RAEGuard S is a permanently installed single-gas detector available for a range of gases including: carbon dioxide (CO2), carbon monoxide (CO), chlorine (Cl2), hydrogen sulfide (H2S), hydrocarbons (HC or TVOC), methane (CH4), oxygen (O2), and sulfur dioxide (SO2). It is a flexible detector that provides analog (4-20mA) or digital (RS-485, ModBus, RTU) signals. The RAEGuard S uses a "smart" sensor module that can be calibrated offline. It is packaged in an explosion-proof, stainless-steel enclosure, making it ideal for hazardous environments. All models include a digital display for viewing gas concentration readings and alarms.

o The RAEGuard PID is a fixed gas monitor with a photoionizations detector for total volatile organic compounds (VOCs). It is housed in an explosion-proof case and carries intrinsic safety certifications. It is compatible with existing analog (4-20mA) or digital (RS-485, ModBus, RTU) signal-based monitoring systems.

o The FM-60 Controller can be configured as a single-channel controller, 1- to 4-channel controller, or 16-channel 4-20 mA controller with 64 addressable ports.

o The MeshGuard is a rugged wireless flammable gas monitor designed for fast deployment, either temporary or permanent. Units placed within 300 meters of each other maintain reliable radio signal pathways in a self-healing network. The MeshGuard has IP-65 and intrinsic safety ratings and provides local audio and visual alarms. Each unit's results are displayed and transmitted wirelessly to the FMC-2000 multi-channel controller.
