Product Description

Product Overview

The VQ22 is an improved, poison-resistant combustible gas detector element designed for the detection of combustible gases, particularly methane in air mixtures, from 0.1% concentration upwards. It features two matched elements and offers no interference from water vapour or carbon dioxide. The VQ22 is engineered for use in atmospheres potentially containing traces of silicone and other poisoning agents, ensuring reliable performance. When used with the recommended bridge circuit and mounting arrangement, it provides a minimum sensitivity of 10 mV/% methane.
