The SEMTECH family of portable on-vehicle emission test systems is based on years of intensive development of portable emission test systems by Sensors' engineering department whose expertise in gas analysis stretches over 35 years.

Sensors, Inc. is the leading provider of in-use emission measurement systems for a variety of applications, world-wide.

SEMTECH portable emissions measurement systems (PEMS) provide immediate laboratory quality analysis of key exhaust gas components, including total hydrocarbons, oxides of nitrogen, carbon monoxide and carbon dioxide. Using Sensors’ proprietary NDUV (non-dispersive ultra violet spectroscopy) module, the NO and NO2 constituents of NOx can be measured simultaneously and independently.

At 22"D x 17"W x 14"H, SEMTECH-DS is little larger than a piece of carry-on luggage. The system can be rack mounted, and is ruggedized for use in both on- and off-road applications.
