Archigas TCD Technology:

Fast & Precise Gas Analyzers
for Hydrogen (H₂) Helium (He)

„We use the TCD3000 SiA in an AEM electrolysis test bench. The sensor is characterized by a very stable measurement signal and low drift with simple and uncomplicated calibration. Even the smallest quantities of gas are sufficient to obtain plausible values.

By using the sensor in the oxygen line of our electrolysis systems, we can quickly and reliably detect hydrogen crossover across the membrane and potential membrane and seal damage very accurately.

The sensor itself can be implemented and put into operation easily and without great effort. A practical feature is that it can also be installed in confined spaces due to its compact size. We will be equipping further systems with the device.“

“We use the Archigas TCD3000 in electrolysis to determine the hydrogen crossover on the oxygen side and the purity on the hydrogen side. The sensors work precisely and react very quickly to changes in gas quality. They also cope very well with any moisture or residual caustic. 


Another great advantage is that the gas quality can be reliably determined throughout operation without major changes to the system.

Implementation and handling are easy: the sensors are installed in the gas path and can simply be read out via a current signal.”

“We use the solution in the areas of catalyst testing and contract research. The device is durable and accurate.

We can ABSOLUTELY recommend it and will continue to use it in the future. In our application, it has replaced an expensive quadrupole mass spectrometer.”

“We monitor, measure and control the atmosphere in our electrode boilers. This is because the boilers heat the water with electrodes and separate the water into various gases.

We require to control the atmosphere in the electrode boilers and have chosen to use technology from Archigas.

Alongside, that we have good experience with this technology, we also experience professional dialogue with Archigas staff.”

“We use the TCD3000 Si from Archigas to determine the gas composition of the product gas in a test setup for zinc interstage electrolysis.

The device is able to detect from 0-100% hydrogen content with high accuracy, which is absolutely essential for the application. We obtain a stable signal without any significant noise or drift. And even with high humidity and even condensing conditions in the sample gas, the sensor delivers a reproducible signal.

Thanks to clear documentation and a well thought-out communication protocol, installation and commissioning are easy. Communication between the PC and sensor is stable.

We would also like to use the device for a later application with high pressure. If we have any questions or queries for Archigas, they respond quickly and helpfully.”

“The environment at Le Mans this year gave us the perfect opportunity to test the Archigas sensors. The tests were very successful: The measurements were fast and accurate – they were exactly what we were looking for.”

“We hereby confirm our recommendation of Archigas as a trusted and reliable manufacturer of gas sensor products. In particular, we would like to highlight the TCD3000Si model, which we have used in our projects.

Based on our experience and cooperation with Archigas, we have found the TCD3000Si and their other products to be of high quality and performance. Their support and technical service have met our expectations, and we are satisfied with the outcomes of our projects involving their technology.

We confidently recommend Archigas and their TCD3000Si product to other potential customers or partners who are considering their solutions.”
