Superior Technology in Gas Detection
GDSFX Infrared Sensor Fixed Gas Detectors offer advanced technology that detects flammable-explosive, suffocating and refrigerant gases with high sensitivity. The user-friendly LCD display provides real-time data display and easy readability. The interactive menu, 4-20mA analog and Modbus RS485 communication features allow easy integration of the detector into control systems and centralized monitoring. It provides ease of use and high productivity with its specially designed menu for users.
GDSFX Infrared Series detectors do not require frequent calibration and have a long service life. Thanks to infrared sensor technology, they do not measure based on chemical reactions and are not affected by environmental disturbances. This means high performance and lower maintenance.
GDSFX Infrared Fixed Gas Detectors guarantee excellent detection in all conditions with an advanced micro-controller chip and embedded software algorithm on the smart circuit board. GDSFX series devices can be used standalone or integrated into control and automation systems with digital relay outputs (NOC adjustable), 4-20mA analog output and Modbus output. It ensures personnel and facility safety by reacting quickly to gas detection at lower and upper alarm limits.
- Sensor handling algorithm for long sensor life and less frequent calibration
- Up to 3 years of sensor life
- High resolution LCD display for clear view and easy reading
- Modern gas level indicator showing current readings
