The SB series achieves a dramatic reduction of power consumption in semiconductor gas sensor applications. The average power consumption of 120mW is required to detect methane, propane or other gases. Using this design, increased sensitivity and improved cross sensitivity allow gas detection with a quick response to be achieved.
We design and manufacture gas sensor equipment in the SB range to detect Methane, Propane/Butane, Carbon Monoxide, Hydrogen, Refrigerants, Alcohol, Indoor Air Quality, Organic Solvents and Carbon Monoxide- Methane.
