Industrial Gas Leak Detectors

Archigas GmbH manufactures an industrial gas leak detector based on TCD (Thermal Conductivity Detector) technology. The detectors are designed for leak testing in critical applications, including integration into process lines, test benches, and analytical equipment, in industrial and laboratory environments requiring continuous gas monitoring.
Measurement is performed directly in the gas flow, without sampling or removing gas from the system. TCD detectors can detect even the smallest leaks, operate at pressures up to 200 bar, and in high-humidity conditions.

FAQ

Archigas GmbH is a gas leak detection company specializing in the development and manufacture of industrial gas analyzers based on TCD technology for engineering systems. Unlike companies that primarily provide services or assemble solutions based on third-party sensors, Archigas manufactures its own TCD sensors and integrates them into clients’ industrial and laboratory installations.
It is a gas analyzer integrated directly into the gas line and used as a detector for gas leak in industrial and scientific applications, providing fast and accurate measurements.
A professional gas leak detector operates continuously in the process circuit, integrates into industrial automation systems, and is designed for leak testing in critical applications. Portable devices are used for one-time checks and are not designed for long-term integration.
The measured value drift is <100 ppm per week, and reproducibility is <100 ppm. These parameters ensure reliable results during continuous operation in industrial conditions.
The TCD3000 SiA and TCD3000 Si detectors are rated for process gas pressures from 0.9 to 200 bar. Pressure reduction devices and bypass circuits are not required – the gas analyzer is installed directly in the line and operates under standard process conditions.
