  • Measurement speed: 30 ms response time, T90
  • Measurement range: from a few ppm to 100 vol.%
  • Operating pressure: up to 200 barg
  • Moisture resistance: condensate and liquid do not damage the sensor
  • Low flow dependency: flow influence on readings
  • Reading stability: measured value drift
  • Easy maintenance: individual factory calibration by the gas analyzer supplier Archigas prior to delivery; recalibration by the customer every 6 months is recommended
  • Environmental safety: zero emissions to the environment
  • Efficiency: reduced losses of costly gas, improved overall system efficiency, lower operating costs
  • Electrolyzers (hydrogen purity monitoring, crossover detection)
  • Fuel cells
  • Recovery systems
  • Process gas purity monitoring systems
  • Monitoring of gas mixtures in transportation and storage
The TCD3000 SiA and TCD3000 Si gas analyzers utilize TCD (Thermal Conductivity Detector) technology. The operating principle of TCD is based on the difference in thermal conductivity of various gases. The technology is optimal for gases with high thermal conductivity (H₂, He) and provides signal linearity across the entire measurement range.

The Gases Archigas Analyzes

Archigas TCD gas analyzers were originally developed for the demanding requirements of the hydrogen industry. However, the technology is equally effective for measuring helium. Today, Archigas offers ready-made solutions for both gases and can adapt them to other binary and quasi-binary mixtures.

Hydrogen

The TCD3000 SiA gas analyzer detects explosive hydrogen concentrations in real time, for example to monitor the lower (LEL) and upper (UEL) explosion levels.
The explosion-proof design (ATEX Zone 1) allows the instrument to be installed directly in a hazardous environment (subject to the installation and operating requirements as defined in the technical specifications).

Helium

The TCD3000 Si gas analyzer is mounted directly in the process and requires no helium extraction from the system.
Direct inline installation eliminates losses of costly gas, critical for recovery systems.

Other Gases

Archigas devices also detect
CO₂ · CH₄ · N₂ · O₂ · Ar · SF₆ · NH₃ · NO₂ · Ne · Kr · Xe · D₂
in binary or quasi-binary mixtures.

Why Archigas Uses TCD Technology

Archigas uses TCD technology because it is particularly effective for measuring the concentrations of hydrogen, helium and other gases in binary and quasi-binary gas mixtures.
TCD technology is ideally suited for H2 und He because of their exceptionally high thermal conductivity relative to other gases. This enables fast, stable, and accurate results even under demanding industrial conditions at high pressure, humidity, and varying mixture compositions.
Engineers choose Archigas when accurate data is needed without complex sample preparation, without frequent maintenance, and no gas losses.

Direct physical measurement without chemical reactions
Very high response speed
Long-term stability
Ability to operate in aggressive and explosive environments
Minimal influence of moisture and contaminants
Simple and reliable design

Trusted in research and industry: What users say

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.
H2i GreenHydrogen GmbH
DI Stefan Kolar
H2i GreenHydrogen GmbH
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 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.
