CH4 Methane Gas Detector GTQ-XP4000 Explosion Proof Combustible Gas Detector

Description

The GTQ-XP4000 stands out as an infrared-based explosion proof combustible gas detector with strong anti-poisoning capability, targeting long-term stable detection in complex industrial atmospheres. It features a full explosion and dust ignition proof design, ensuring safe operation in explosive hazardous areas. Adopting an infrared detection principle, it shows excellent resistance to silicon, sulfur and halogen compounds, greatly extending sensor service life and reducing maintenance frequency. It is equipped with dual-channel relay output, supporting independent high and low alarm threshold control for precise risk grading. The digital sensor assembly can be replaced without field calibration, and the IP66 protection level ensures reliable performance in harsh environments. It integrates a two-stage built-in sound-light alarm and a high-brightness digital tube display for clear alerts. A standard expansion port supports 4-20mA, HART, RS485 and relay output, enabling flexible access to various monitoring platforms. It is a high-end choice for refractory flammable gas monitoring in petrochemical and chemical industries. ● Explosion and dust ignition proof protection, compliant with hazardous area standards for personnel and assets protection ● Infrared measurement method, resistant to silicon-sulfur and halogen poisoning ● Two-channel relay output, with separate high alarm and low alarm settings ● Digital sensor assembly, replaceable without on-site calibration, easy to replace or maintain ● IP66 protection grade, built to withstand harsh working conditions ● Built-in two-stage sound and light alarm for clear hazard notification ● High-brightness nixie tube display for easy concentration reading ● Standard expansion port supporting 4-20mA / HART / R485 / relay output
