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.

Areas of application

Archigas’ advanced thermal conductivity meters offer precise solutions for safety and process applications. They measure hydrogen in electrolysis and fuel cell systems, monitor hydrogen concentrations in natural gas and are ideal for helium and hydrogen leak detection. The devices are predestined for monitoring and reducing emissions in decarbonisation projects and promote the highest product quality in various industries.

Electrolysis

Monitoring of OEL / UEL and purity, e.g. for H2 electrolysis

Fuel cell

Monitoring the hydrogen concentration in the exhaust gas train

H2 in natural gas

Determination of the hydrogen content in natural gas networks up to 100%

Leak testing (leakage)

Automated detection of leaks for monitoring

Further areas of application

Purity control, purge gas monitoring, measurement of other binary or quasi-binary gas mixtures

What our clients say

„We measure the hydrogen concentration in electrode boilers. This is because the boiler heats water with electrodes, and the water divides into H2 and O2. Both are explosive, and we therefore have a natural motivation to monitor the concentrations. That is the usage of the TCD 3000. The signal goes directly into our monitoring system allowing us to control the atmosphere via adjusting N2 flow and timing. We have very good experience with the product, it works for us through the professional dialogue with Archigas staff.“
Morten Hildebrandt Jensen
Fjernvarme Fyn
“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.”
Erik Delp
Frankfurt University of Applied Sciences
“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.”
