Product Description
Product Overview
The VQ25 Combustible Gas Detector Elements are designed for the detection of combustible gases in air, offering robust performance even in high concentration environments (up to 100%). These matched elements are particularly suitable for applications where exposure to flammable gases is likely. The VQ25 is also effective for detecting combustible vapors containing halogens and is generally unaffected by water vapor or carbon dioxide unless their concentrations impact flammability. With a recommended bridge circuit, the VQ25 provides a minimum sensitivity of 25 mV/1% n-butane.Product Attributes
