Sensors introduces NO/NO₂ measuring instrument

3 July 2003

Saline, MI-based Sensors Inc. announced the SEMTECH NO/NO₂ 200 emissions analysis unit for the measurement of nitric oxide and nitrogen dioxide concentrations.

The SEMTECH NO/NO₂ 200 provides accuracy within &plusm;3% of the reading, or 15 ppm, whichever is greater, for both NO and NO₂. For both gas constituents, resolution is 1 ppm and linearity is &plusm;1% of the reading or 5 ppm, whichever is greater.

The SEMTECH NO/NO₂ 200 utilizes an electrodeless lamp (EDL). Discrete spectral lines emitted by the EDL correspond to adsorption wavelengths for NO and NO₂, eliminating the need for an NO₂ to NO converter. The use of specific wavelengths also eliminates the risk of interference from water vapor in the non-dispersive ultraviolet (NDUV) analyzer, which is used in other models of SEMTECH instruments by Sensors. The EDL is warranted for 20,000 hours.

The SEMTECH NO/NO₂ 200 has been designed to offer cost-effective, lab-quality performance under continued field-use conditions. It can be used for such tasks as monitoring engine performance of vehicles in use, R&D of engines and emission control equipment, or testing in end-of-the-line production environments.
