Explosion-Proof Hydrogen Cyanide Gas Detector | IECEX ATEX Sensor

Description Overview Introducing the SG100-WH, a fixed gas detector engineered for the continuous monitoring of Hydrogen Cyanide (HCN) gas in hazardous environments. With full IECEx and ATEX certifications (Ex db IIC T6 GB), this detector guarantees high-level safety and reliability. The SG100-WH is equipped with a 3-wire 4-20 mA analog output, as well as HART and RS485 Modbus protocols, making it compatible with most industrial control systems. Its intelligent hot-swappable sensor design and magnetic wand allow for safe and simple calibration and maintenance by a single person, without needing to disassemble the entire unit.   Features International Safety Certifications: Meets IECEx and ATEX standards for safe operation in explosion-prone zones. Smart Modular Design: The hot-swappable sensor can be replaced without disassembling the main unit, minimizing downtime during calibration or service. Effortless Operation: Features a magnetic wand for safe menu navigation in hazardous areas and allows for easy one-person calibration. Flexible Connectivity: Supports 4-20 mA analog output, HART, and RS485 Modbus for seamless system integration. Rugged and Durable: IP66/IP67 rated for complete protection against dust and water ingress. Convenient Installation: Weighing only 1 kg, it can be easily installed by a single technician.   Technical Specifications Specification Description Detected Gas H2S, CO, O2, EX, CH4, VOC, CL2, HCL, NO, NO2, SO2, NH3, etc different single gases.
