SGA – OEM Single Gas Sensor Enclosure

Precision measurement of a single gas with broad application and implementation.

If you are looking for industrial NDIR sensors, SSi is ready to fill some of the gaps formed by the departure of VTI-Valtronics (Val-tronics) from the market. We manufacture and develop technology to measure dew point, oxygen, CO, CO2, CH4 and H2. We package the sensors based on the customer applications. If you would like to discuss any of our products in more detail, don’t hesitate to contact us.
