Product Description
VQ10 Combustible Gas Detector Elements
The VQ10 is a pair of matched elements designed for the detection of combustible gases, with a particular focus on methane in air mixtures. It offers reliable detection from 0.1% concentration upwards and is unaffected by water vapor or carbon dioxide. Utilizing a recommended bridge circuit, the VQ10 achieves a minimum sensitivity of 15 mV/% methane. Its low power consumption makes it ideal for battery-operated systems and applications where power minimization is critical. The elements are supplied as a matched pair with a trimming resistor (68-220 ) to be connected across the compensator element.
