Ensure absolute workplace safety with our high-performance split hydrogen chloride gas detector, specifically engineered for real-time monitoring of corrosive HCl gas leaks in chemical processing and industrial environments. Utilizing advanced electrochemical sensor technology, this instrument delivers exceptional measurement accuracy, rapid response times, and long-term operational stability.

Designed to accommodate diverse industrial monitoring needs, the detector offers versatile measurement ranges including 0-20 (50) ppm, 0-200 (400) ppm, 0-1000 (2000) ppm, and 0-3000 (6000) ppm. It incorporates a rugged die-cast aluminum housing and a clear 2.5-inch high-definition color LCD display showing real-time gas concentration, ambient temperature, and humidity.

The split design physically separates the display host from the electrochemical probe using a customizable extension cable (up to 5-10 meters or longer), enabling safe remote monitoring in hazardous zones. It supports standard 4-20mA, RS485 (MODBUS-RTU), and wireless signal options (LORA, ZigBee, 4G), alongside a passive relay contact output for direct integration with PLCs, DCS, and emergency ventilation systems.


Built with an Ex d IIC T6 explosion-proof rating and IP66 water and dust resistance, the unit performs reliably under harsh operating conditions from -20°C to 50°C. It is widely applied across chemical plants, pharmaceutical manufacturing, semiconductor facilities, metal smelting, and hazardous waste treatment plants where corrosive hydrogen chloride is handled.

It is used for continuous, real-time detection of hydrogen chloride ($HCl$) gas leaks in industrial settings, instantly triggering local audio-visual alarms and activating safety interlocks like exhaust fans via relay outputs to prevent toxic exposure.
The split configuration allows the sensitive electrochemical probe to be positioned directly near high-risk leakage points while keeping the display and control unit in a safer, accessible location, protecting electronics from corrosive gas exposure and simplifying calibration.
The detector utilizes a plug-and-play modular sensor architecture. When maintenance or sensor replacement is needed, individual components can be serviced independently without discarding the entire assembly, significantly saving operational costs.
