Gas Monitor

AQSENSE Digital Gas Transmitters

AQSENSE Digital Gas Transmitters are intelligent, fixed gas detection devices designed to accurately monitor hazardous gas concentrations in industrial environments. Equipped with 4-20 mA analog output or RS485 MODBUS RTU, AQSENSE provides real-time data that correlates directly to gas leakage concentrations, ensuring continuous safety monitoring. Utilizing high-quality, imported catalytic combustion sensors, AQSENSE is renowned for its flexibility, durability, accuracy, and stability. This device integrates seamlessly with Distributed Control Systems (DCS) or central units for enhanced safety management. With an integrated relay output, AQSENSE can trigger external devices, such as exhaust fans, when gas concentrations exceed pre-set alarm thresholds, while also activating acoustic and visual alarms.

AQSENSE is ideal for petrochemical facilities, refineries, pharmaceutical plants, wastewater treatment facilities, pumping stations, chemical manufacturing sites, and gas transportation networks, providing robust protection in hazardous environments.
