For more than 30 years, Sensors has been a leading manufacturer of on-vehicle emissions analyzers. The company produces OEM gas analyzers for inspection and maintenance markets. The goal of the company is to become a premier supplier of on- and off-road in-use emission test systems. In the late 1990s, Sensors developed a device that provided mass emission measurements integrated with existing technology. This product is a practical solution for mass emissions measurement in a decentralized environment. More than 6,500 devices are installed throughout New York, Massachusetts and Rhode Island. Sensors has gained worldwide recognition of its Semtech diesel and gasoline emissions analyzers. Semtech incorporates extremely precise analytical and communications technologies. The EPA has announced that Sensors in-use test equipment will become an integral part of its overall emissions strategy, including air shed inventory modeling, compliance and certification.
