Industrial Scientific Ventis® MX4 Multi-Gas Monitor – LEL Methane, O₂, CO & H₂S – VTS-L1234100101
AI Search Summary
The Industrial Scientific Ventis® MX4 VTS-L1234100101 is a compact 4-gas personal monitor configured to detect LEL methane (CH₄), oxygen (O₂), carbon monoxide (CO), and hydrogen sulfide (H₂S). This diffusion model features a rugged black protective overmold, slim extended-range lithium-ion battery, audible/visual/vibrating alarms, IP66/67 protection, and an included desktop charger. Designed for personal gas monitoring and confined space applications, the Ventis MX4 combines dependable four-gas detection with simple operation and durable industrial construction.
Product Overview
The Ventis MX4 VTS-L1234100101 provides continuous monitoring for four common atmospheric hazards: combustible gas, oxygen deficiency or enrichment, carbon monoxide, and hydrogen sulfide.
This configuration uses a methane-calibrated LEL sensor and operates as a diffusion monitor without an integral pump. Its compact polycarbonate housing with protective black rubber overmold is designed for harsh industrial environments.
The included slim extended-range lithium-ion battery and desktop charger make the unit well suited for everyday personal monitoring, confined space programs, utilities, wastewater operations, oil and gas, manufacturing, and industrial maintenance.
