NDIR multi-gas sensors provide cost effective precision for a multitude of environmental monitoring applications

The m-u-t multi-gas sensor measures the concentrations of up to eight optically active gases using non-dispersive infrared spectroscopy (NDIR) technology. Operators can also integrate up to six other sensors with different measuring principles, such as electrochemical, as well as temperature and relative humidity sensors. These versatile and precise multi-gas sensors have been developed for use as OEM components for integration into online analysis systems, for applications such as process control, for permanent installation and are made for use in monitoring applications. The infrared multi-gas sensor has a non-extractive sample feed; the gas sample is transferred into the measuring chamber thanks to a difference in pressure conveying the sample.

These sensors use a broad-band IR emitter and a proprietary nine-channel detector with bandpass filters of specific wavelengths depending on the type of gas to be analysed. It measures light absorption as it crosses the sample chamber to provide a precise reading of gas concentration. There are no chemical reactions, therefore these multi gas sensors have a long service life and provide long term stability.

The sensors are pre-calibrated and compensated for cross-sensitivities according to the customers’ gas matrices. They are CE certified and housed in a IP20 rated housing. m-u-t’s versatile sensors provide OEMs with a versatile, precise and long-lasting device that can monitor a host of environmental pollutants with rest-assured accuracy ensuring that end-users comply with environmental regulations and safeguard the safety of their personnel, assets and the local community.
