GasDog Gas Detectors not only provides portable gas detectors, fixed gas detectors, multi gas detectors, industrial gas detectors, explosive gas detectors and gas analyzers, but can also provide new technical solutions according to customers special requirements. GasDog Gas Detectors have been widely used in the detection and analysis of various gases in Industrial Safety, Mining Operations, Confined Spaces, Oil and Gas Industry, Environmental Monitoring, Residential Safety, Laboratories, Waste Management and other industries. Currently, the maximum measurement range of GasDog Gas Detectors is 0~2000ppm. You can choose the gas detector you need based on the measurement method (portable/fixed), gas type, gas quantity (single gas/multi gas), and measurement environment (industrial environment, explosive occasions). For example, the Handheld 4 in 1 Multi Gas Detector can simultaneously measure CO (0-1000ppm), H2S (0-100ppm), O2 (0-30% VOL) and EX (0-100% LEL) gases. The Handheld Hydrogen (H2) Gas Detector can safely measure Hydrogen (H2) Gas in the 0 to 500ppm/1000ppm/2000ppm/5000ppm measurement range in explosive environments.
