TCD3000 Si + SiA: ultra-compact screw-in sensors for hydrogen and helium — response under 30 ms, up to 200 bar, ATEX Zone 1 available.

Archigas GmbH, based in Rüsselsheim am Main, is a German manufacturer of innovative gas analyzers built on thermal conductivity detection (TCD) with micromechanical MEMS sensor technology. Developed by physicists and recognized with the Hermes Startup Award, our award-winning, ISO 9001-certified solutions are engineered for the hydrogen and helium economy — electrolysis, fuel cells, H2 in natural gas, gas purity, and helium leak detection and recovery.

Our portfolio centers on two ultra-compact screw-in analyzers. The TCD3000 Si is designed for H2 and He measurement in non-hazardous areas, while the TCD3000 SiA is the first screw-in type with ATEX Zone 1 certification (II 2 G Ex db IIC T4/T3 Gb), ideal for safety-critical environments.
