VM840 4-in-1 Gas Detector with Alarms
This compact 4-in-1 gas detector monitors combustible gas (LEL), CO, H₂S, and O₂ with high-accuracy plug-in sensors. Designed for industrial safety, confined spaces, and hazardous environments, it features rapid response (<30s), multiple alarm types (gas, sensor, battery), and IP65 explosion-proof protection. The diffusion-type sampling and rechargeable lithium battery ensure reliable, continuous monitoring with automatic self-check functions for added peace of mind.
