Cutting-Edge Technology in Gas Detection

GDSFX Fixed Gas Detectors with Infrared Sensors feature advanced technology that detects flammable, explosive, asphyxiating, and refrigerant gases with high sensitivity. Their user-friendly LCD screen provides real-time data display and easy readability. Its on-screen menu, along with 4–20 mA analog and Modbus RS485 communication capabilities, enables easy integration of the detector into control systems and facilitates centralized monitoring. The menu, specially designed for users, ensures ease of use and high efficiency.

GDSFX Infrared Series detectors do not require frequent calibration and have a long service life. Thanks to infrared sensor technology, they do not rely on chemical reactions for measurement and are not affected by environmental interference. This translates to high performance and lower maintenance requirements.

GDSFX Infrared Fixed Gas Detectors guarantee excellent detection under all conditions thanks to the advanced microcontroller chip and embedded software algorithm on their smart circuit board. GDSFX series devices can be used independently or integrated into control and automation systems via digital relay outputs (NOC adjustable), a 4-20 mA analog output, and a Modbus output. They ensure personnel and facility safety by providing a rapid response when gas is detected at the lower and upper alarm limits.
