A 4-gas meter measures carbon monoxide (CO), oxygen (O2), hydrogen sulfide (H2S), and combustible (EX-LEL) gases. Used for confined spaces such as tanks, vessels, silos, and tunnels. Maritime, oil and gas, construction, mining, water, and wastewater are just some of the industries that make use of 4 gas monitors.

4 Gas Monitors, Meters & Multi-Gas Detectors

Ensuring workplace safety and environmental compliance requires reliable gas detection equipment designed for industrial, commercial, and residential applications. Our comprehensive selection of gas monitors, gas meters, and multi-gas detectors provides accurate measurement and early warning systems for hazardous gas concentrations across diverse industries.

4 Gas Monitors for Continuous Safety Monitoring

Professional gas monitors deliver real-time atmospheric monitoring for confined spaces, manufacturing facilities, and industrial environments. These fixed-point detection systems continuously monitor ambient air quality, providing immediate alerts when dangerous gas levels exceed predetermined safety thresholds. Essential for petrochemical plants, wastewater treatment facilities, and underground mining operations, gas monitors ensure 24/7 protection against toxic gas exposure, combustible gas accumulation, and oxygen deficiency hazards.

Precision Gas Meters for Accurate Measurement

Portable gas meters offer versatile gas detection capabilities for field technicians, safety inspectors, and emergency responders. These handheld instruments provide precise gas concentration readings for leak detection surveys, pre-entry safety checks, and environmental monitoring applications. Gas meters feature calibrated sensors for detecting methane, hydrogen sulfide, carbon monoxide, and other hazardous gases in utility maintenance, HVAC servicing, and industrial maintenance procedures.

Multi-Gas Detectors for Comprehensive Protection

Multi-gas detectors combine multiple sensor technologies in single portable units, simultaneously monitoring up to four different gases including LEL (Lower Explosive Limit), oxygen, carbon monoxide, and hydrogen sulfide. These versatile instruments are indispensable for confined space entry, permit-required space monitoring, and personal protective equipment applications. Multi-gas detectors provide comprehensive atmospheric testing for construction sites, marine environments, chemical processing facilities, and emergency response scenarios.

Applications Across Critical Industries

Our gas detection equipment serves essential applications in oil and gas exploration, chemical manufacturing, pharmaceutical production, food processing, mining operations, municipal utilities, and environmental consulting. From leak detection and fugitive emissions monitoring to worker safety compliance and air quality assessment, these instruments meet stringent safety standards including OSHA, NIOSH, and ATEX certifications.

Perfect for continuous area monitoring, portable leak detection, or personal safety protection, our selection of professional-grade gas monitors, meters, and multi-gas detectors ensures accurate detection, reliable performance, and regulatory compliance for your critical safety applications.
