GfG Oxygen & Toxic Gas Sensor Transmitter

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:

This flexibility makes the EC22D a strong standardisation platform across multi-site operations.

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:

This ensures fast local response, even before central systems react.

Accurate, Stable & Low Maintenance
Engineered for long-term reliability, the EC22D features:

These features reduce maintenance requirements while maintaining dependable performance.

The EC22D is built to withstand the conditions typical of service areas, utilities, and light industrial sites.
