Standgas Pro LCD TOX Duran Electronica
The STANDGAS PRO LCD TOX is a standalone, programmable detector designed for the detection of toxic gases and oxygen. It employs electrochemical technology for toxic gases and infrared technology for detecting CO2 and A1 safety-grade refrigerants, with additional early detection of hydrogen in battery rooms.
This detector features:
- A 16 x 2 line backlit display
- Three control keys
- Programmable alarm relay output
- Internal acoustic alerts
Special Functions for Toxic Gases:
- Digital monitoring of sensor status
- Automatic hardware status checks
- Digital filtering with variable sampling of the sensor’s average values
- Automatic temperature compensation for accurate response to temperature changes
- Infrared sensors with microprocessor control for temperature compensation, linearization, and calibration parameter storage
- Easy installation replacement without needing recalibration or additional gas
Additional Features:
- Standalone operation without needing a control center
- Mixed functionality: local information and operation with RS485 communication to a control center
- IP65 protection grade
- Optional universal support for ceiling or floor installation
- Optional 230V power charger that can connect 1 to 10 STANDGAS detector units
