RAE Systems Introduces QRAE II Next Generation One-to-Four Sensor Toxic Gas Monitor.

First Unit Designed With Lead Free, RoHS Compliant Oxygen Sensor 

SAN JOSE, Calif. -- RAE Systems Inc. (AMEX:RAE), a leading global provider of rapidly deployable sensor networks that enable customers to identify safety and security threats in real time, today introduced QRAE II, the next generation in basic one-to-four sensor, toxic gas, worker protection. This new monitor includes a patented, solid-polymer electrochemical (SPE), lead free, oxygen sensor. It also features easy access to the battery compartment and all of the sensors including the oxygen, combustible, carbon monoxide and hydrogen sulfide sensors. The QRAE II is designed and certified for use in hazardous environments including oil refineries, petrochemical plants, steel mills, wastewater treatment plants, landfill operations, coal mines, sewers, trenches and other confined space entry operations.

"The QRAE II is the first product to use our patented, lead free, RoHS compliant, next generation, longer life, solid polymer oxygen sensor," said Thomas Negre, RAE Systems' Global Product Director for Instrumentation Products. "This is a global product that supports eight languages and three character sets. It has been designed and tested to have the best EMI/RFI noise immunity in the industry to prevent interference from cell phones and handheld walkie-talkies."

The QRAE II is the first gas detector to include a lead-free oxygen sensor designed to meet the new global directives on the Reduction of Hazardous Substances (RoHS), including lead. The instrument can be powered by either rechargeable lithium-ion batteries or standard alkaline batteries. The large display on the QRAE II can be electronically flipped to the orientation of the worker for either handheld or belt mounted operation. The QRAE II also includes a new visual graph display in addition to the actual sensor readings.

The QRAE II features easy access to the filters, battery and sensors with out exposing the electronics, making field changes both safe and quick. The product has both CSA (for use in the Americas) and ATEX (for use in Europe) certifications for safe use in potentially explosive environments. The rugged instrument is IP-65 rated for water and dust resistance. The unit supports eight languages including: Chinese, English, French, German, Italian, Korean, Portuguese and Spanish. The operator interface is the proven two-button system pioneered by RAE Systems to work even with dual-layer gloves. The unit includes vibration, flashing LED and loud 95dB audible alarms to keep workers safe and aware in a mix of environments. Calibration is done quickly and easily with a single button or when docked to the AutoRAE calibration and bump test station.

The QRAE II will be offered alone or in a confined space entry kit that includes tubing, sample probe, air pump, tool kit, calibration gases and a hard case. QRAE II is compatible with AutoRAE for automated charging, bump testing and calibration.
