Fixed Hydrogen Combustible Toxic Gas Detector with 4-20mA Output – GAOTek

Description Overview This fixed gas detector is designed for continuous monitoring of hydrogen, combustible gases, toxic gases, O2, VOC, and CO2 in industrial environments. It features natural diffusion sampling with fast response times (LEL: T90≤15s, toxic gas: T90≤30s) and offers multiple output options, including 4-20mA analog and PBUS digital signals. Housed in a robust aluminum alloy or stainless-steel enclosure with IP66/67 protection and explosion-proof certification (Ex d IIC T6 Gb), it is built for reliability in hazardous areas. The device includes two free-contact relays and one active relay for alarm integration and is operable via IR remote control.   Features Detects hydrogen, combustible gases, toxic gases, O2, VOC, and CO2 Fast response times: LEL (T90≤15s), toxic gas (T90≤30s) Multiple outputs: 4-20mA analog and PBUS digital Explosion-proof certification: Ex d IIC T6 Gb / Ex tD A21 IP66/67 protection for dust and water resistance IR remote control for easy operation Two free-contact relays and one active relay for alarm integration Durable aluminum alloy or stainless-steel housing   Technical Specifications Parameter Specification Target Gases Hydrogen, Combustible Gas, Toxic Gas, O2, VOC, CO2, Freon Sampling Method Natural Diffusion Response Time LEL: T90≤15s, Toxic Gas: T90≤30s Output Signals 4-20mA, PBUS Relays 2 Free Contact, 1 Active Relay Control Method IR Remote Control Explosion Protection Ex d IIC T6 Gb / Ex tD A21 Ingress Protection IP66/67 Power Supply DC24V±6V, ≤2.5W Housing Material Aluminum Alloy / Stainless Steel Dimensions 130mm x 154mm x 95mm Weight 1.2kg
