Thermal conductivity gas analysers measure the concentration of H2, He and Ar gases in a given atmosphere. These gas analysers are used, for example, in semiconductor production, leak detection in industrial gas systems and air quality monitoring. Thanks to their reliability and accuracy, thermal conductivity gas analysers guarantee the quality and safety of industrial processes.

For furnaces, metallurgy, semiconductor industry and gas separation.
The ZAF thermal conductivitygasanalyser continuously measures the concentration of gases such asH2, He and Ar with high stability.
It is also available in a version for potentially explosive atmospheres (for countries outside the European Union): ZAFE certified Ex NEPSI.
Since thermal conductivity varies from one component to another, any change in the concentration of the measured component causes a variation in the thermal conductivity of the sample gas, which in turn affects the temperature of the platinum wire.
Theanalyser uses these temperature variations to determine the gas content.
Custom Measurement Scales
Measurement scales are flexible and depend on the specific components. In this way, the device can be adapted to specific monitoring requirements.
Measurement accuracy
Fast Response Time
Response time is optimized for increased efficiency. The standard version guarantees a response time of ≤ 60 seconds, while the fast-response version reduces this to ≤ 10 seconds.
Multi-purpose outings
Contact inputs (Optional)
Three dry contacts enable advanced functions such as measurement hold, range change and self-calibration start.
User-friendly display
The backlit LCD display provides a clear view of data, facilitating real-time monitoring.
Extended communication options
Optional RS-232C Modbus® communication enables easy integration with other systems.
Simple mounting and universal power supply
Theanalyser is designed for easy panel mounting and accepts a supply voltage range of 100 to 240 Vac, 50/60 Hz.
Compact and lightweight
With dimensions of 192 (W) × 240 (H) × 213 (D) mm and a weight of around 5 kg, theanalyser is compact and easy to integrate into a variety of environments.
