AppliedSensor to Exhibit Hydrogen Sensor Modules
at Sensor + Test 2010

Rapid Detection of Gas Leaks Supports
Continued Development of Future Hydrogen Economy

Warren, New Jersey - June 28, 2010 - AppliedSensor, a designer and manufacturer of chemical sensor components and intelligent indoor air quality (iAQ) modules, announced today that they will introduce the HLS-440P and HPS-100 hydrogen sensor modules at Sensor + Test 2010, May 18-20 in Nurnberg Germany in Hall 12, Stand 331. Both sensors were designed for implementation in fuel cell systems or other in-process applications. The use of Field Effect (FE) Technology ensures that the modules are fast responding and highly sensitive to the presence of hydrogen gas leaks, with no cross detection towards HC, H2S, H2, CO, CO2 or NOx. Integration of either of these hydrogen sensors will enable manufactures and designers of hybrid vehicles to continue using hydrogen as an alternative fuel source.

“The U.S. and E.U. have invested billions to accelerate the development of hydrogen as an alternative fuel source. We can contribute to this future hydrogen economy by providing product designers and users with a highly sensitive module for detecting hydrogen gas leaks,” said AppliedSensor, Inc. CEO Tom Aiken. “Hydrogen must be kept to concentration levels of less than four percent in ambient air and our sensors detect even the slightest fluctuation.”

With an IP6K9 rating and designed towards Atex Zone 2, both the HLS-440P and HPS-100 can be installed virtually anywhere. The selective FE Technology process of the hydrogen sensors is based on the work-function change of the gate layer shown by Metal-Oxide-Semiconductor FE transistor (MOSFET) devices when exposed to a test gas.
