GasDog specializes in multi-gas detection technology, manufacturing portable and fixed 4-in-1 and 5-in-1 gas monitors designed for simultaneous multi-hazard assessment. Backed by an ISO 9001-certified factory setup and 10+ years of R&D, GasDog provides versatile multi-gas instruments that reduce hardware clutter and streamline site inspection workflows.

Key models, such as the GD700-5GAS and GD400-5GAS series, allow simultaneous detection of Oxygen (O2), Combustible gases (%LEL), Carbon Monoxide (CO), Hydrogen Sulfide (H2S), and Carbon Dioxide (CO2) or VOCs via PID sensors. Featuring integrated sampling micro-pumps, dual-mode diffusion capabilities, clear multi-channel displays, and programmable high/low alarm setpoints, these devices deliver comprehensive environmental awareness.

Meeting CE, ATEX, and RoHS safety benchmarks, GasDog multi-gas analyzers are widely deployed in wastewater treatment plants, municipal sewers, marine vessel ballast holds, landfill gas extraction, and agricultural grain silos.

GasDog supports global clients with factory-direct pricing, 7-day custom prototyping, full sensor replacement options, and a 1-year product warranty, providing scalable continuous multi-gas monitoring solutions.
