- Multiple Communication Outputs – Modbus RS485, 4-20mA, and relay contacts
- IP65 Water & Dust Protection – built for harsh environments
- User-Friendly LCD Display for real-time gas concentration monitoring
- Long Sensor Life & Low Maintenance for reduced operational costs
A Multi-Sensor Solution for Every Industrial Need
The GDSFX Series is available in five different sensor technologies, ensuring accurate detection of a wide range of hazardous gases:
-
Catalytic (Pellistor) Sensor – Fast, Reliable Combustible Gas Detection
- Ideal for detecting flammable gases like methane, propane, and hydrogen.
- Uses a pellistor-based catalytic reaction to sense gas leaks rapidly.
- Provides fast response times and cost-effective operation.
-
Infrared (NDIR) Sensor – Precise, Stable Gas Detection with No Calibration
- Detects flammable gases, carbon dioxide (CO₂), and refrigerants.
- Highly stable, with no sensor poisoning and minimal drift.
- Low maintenance with a longer lifespan than catalytic sensors.
-
Electrochemical Sensor – High-Sensitivity Toxic Gas Monitoring
- Specifically designed for toxic gases like carbon monoxide (CO), hydrogen sulfide (H₂S), ammonia (NH₃), sulfur dioxide (SO₂), and more.
- Provides high accuracy at low concentration levels (ppm detection).
- Essential for industries like wastewater treatment, chemical plants, and energy production.
-
Photoionization Detector (PID) – Detects Volatile Organic Compounds (VOCs)
- Used for the detection of VOCs and other hazardous organic compounds.
- Can measure gases at ppm and even ppb (parts per billion) levels.
- Ideal for chemical production, environmental monitoring, and industrial hygiene.
-
Molecular Property Spectrometer (MPS) – Advanced Gas Mixture Recognition
- Capable of differentiating between various gases in mixtures.
- Long sensor life (up to 15 years), requiring no frequent calibration.
- Used for hydrocarbon combustible gases, methane, and refrigerants.
