The XP4000 is a high-performance explosion-proof multi-gas detector tailored for intelligent monitoring of oxygen, toxic gases and VOCs in complex industrial scenarios. It features a robust explosion-proof and dust-ignition-proof structure, complying with global safety regulations for hazardous area equipment. Different from the dual-wire design of the XP3000, this model uses a three-wire terminal structure, making wiring more standardized and suitable for large-scale systematic deployment. The digital sensing module supports calibration-free on-site replacement, ensuring detection stability and reducing maintenance downtime. With an IP66 ingress protection rating, it adapts to severe industrial environments with high dust, humidity and temperature changes. It is equipped with a high-brightness digital tube display, ensuring clear readings even in poor lighting conditions. A standard expansion interface is integrated, supporting 4-20mA, HART, RS485 and relay output, enabling flexible access to different monitoring and control systems. It also provides dual independent relay outputs with separate high and low alarm functions, supporting graded alarm and linkage control. This model serves as a core component for intelligent safety systems, widely used in petrochemical, pharmaceutical, environmental monitoring and other industries requiring high-standard multi-gas detection.
