The TCD3000 SiA H2 gas analyser

The screw-in analyser with microsensor technology enables precise and fast analysis of binary gas mixtures (e.g. H2 in O2) by means of thermal conductivity measurement. With a response time of < 30 ms, a measuring range from a few ppm to 100 vol.% and a functional capability up to 200 bar as well as under humid conditions, it is consistently orientated towards the requirements of the hydrogen industry. Thanks to its long service life, low maintenance, high compatibility and minimal dimensions, it also offers cost, labour and space savings.

What customers are saying

„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 boliers 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."
