Hi,
You're receiving this email because {name} thinks the GfG Oxygen & Toxic Gas Sensor Transmitter would interest you.
The GfG EC22D gas transmitter is a versatile fixed gas detection solution engineered for continuous monitoring of toxic gases, oxygen levels, and hydrogen across a wide range of non-hazardous applications.
Utilising proven electrochemical (EC) sensor technology, the EC22D provides highly accurate, selective measurement of gases such as carbon monoxide (CO), hydrogen sulphide (H₂S), ammonia (NH₃), and oxygen—supporting both life safety and process monitoring requirements.
Flexible Across Building & Industrial Applications
While ideal for HVAC and plant rooms, the EC22D is equally suited to broader fixed gas detection needs, including:
- Car park ventilation control (CO/NO₂ monitoring)
- Laboratories and research facilities
- Battery rooms and hydrogen monitoring
- Water and wastewater treatment plants (H₂S, O₂)
- Food & beverage and cold storage facilities
- Light industrial and manufacturing environments
- Boiler rooms and combustion systems
- Utility infrastructure and energy facilities
This flexibility makes the EC22D a strong standardisation platform across multi-site operations.
- Seamless System Integration
- Designed for modern control architectures, the EC22D supports:
- 4–20 mA analog output for simple integration
- RS-485 Modbus communication for digital networks
- Compatibility with BMS, PLC, and SCADA systems
This enables automated responses such as ventilation control, alarm activation, and system shutdowns—supporting compliance with workplace safety and building standards in New Zealand.
Clear Local Indication & Alarm Response
A built-in 2.2” colour display provides real-time gas readings and system diagnostics at the point of detection.
In alarm conditions:
- Visual indication changes for immediate recognition
- Integrated audible buzzer alerts nearby personnel
This ensures fast local response, even before central systems react.
Accurate, Stable & Low Maintenance
Engineered for long-term reliability, the EC22D features:
- Electrochemical sensing for high selectivity and low cross-sensitivity
- Automatic temperature compensation for stable readings
- Signal linearisation for improved accuracy
- Typical sensor life of 2–3 years
These features reduce maintenance requirements while maintaining dependable performance.
- Robust Design for Real-World Environments
- IP54-rated enclosure for plant rooms and indoor industrial spaces
- Compact, easy-to-install form factor
- Optional accessories for more demanding environments
The EC22D is built to withstand the conditions typical of service areas, utilities, and light industrial sites.
