VM-4 AS Multi-gas detectors can detect multiple gases with a single detector. The multi-gas detector can detect combustible gas, O2, and other two types of toxic gases continuously and simultaneously. It is widely used in areas where explosion-proofing is required or toxic gas leaks, like underground channels or the mining industry, to protect the worker's life and avoid damage to the relevant equipment. VM-4 AS Multi-Gas Detector, which is simple to utilize and supports carbon monoxide (CO), hydrogen sulfide (H2S), combustible gases, and oxygen (O2) exhaustion or enhancement. Presently, with the further development of the identification of pentane, hexane, and other long-chain hydrocarbons, offering you consistency, strength, and minimal expense of possession in an easy-to-utilize arrangement. The multi-gas detector contains a wide scope of amazing components to make regular use simpler and more secure.
