The SB-31 is a tin dioxide semiconductor gas sensor which has a high sensitivity to various solvents. This model is suitable for detecting various solvents in general.

Structure

Gas sensitive semiconductor material is a mini bead type and a heater coil and electrode wire are embedded in the element. The sensing element is installed in the metal housing which uses double stainless steel mesh (100 mesh) in the path of gas flow. The mesh is an anti-explosion feature.

Features

• Purpose: Safety & Security
• Use: Industrial gas leak detector
• Target gas: Organic solvents/VOC/Alcohol
• Max concentration: 10000 ppm
