1.Product Overview
The GTYQ-JSY-201/A industrial-grade point gas detector is an explosion-proof device integrating real-time concentration display, audible/visual alarms, and ambient temperature monitoring.
Operating on natural diffusion principle with catalytic combustion sensing technology, it delivers superior sensitivity and measurement consistency. The industrial-grade segment LCD simultaneously displays gas concentration and ambient temperature. Upon reaching preset thresholds, the unit triggers strobe/horn alarms and can activate ventilation systems. Featuring 4-20mA output for direct DCS integration or RS485 connectivity with our M201 control panel for centralized monitoring. The PowerBus 2-wire option simplifies installation. Built with embedded microcontroller architecture for reliable operation with intuitive functionality.
