H2-Measuring Device TCS
General Information
SWM2000
Oxygen Hydrogen Measuring Device. Main parts are a zirconia oxygen sensor and a TCD for the hydrogen detection. Additionally, further thermodynamic values (or data) can be calculated on the basis of the oxygen/hydrogen measurement. We provide more information on request. Please contact us by e-mail.
SGM5-NGW
This device serves the determination of the Non-Equilibrium-Oxygen (NGW-Sauerstoff in German) in reducing atmosphere. It is mainly used in applications where the equilibrium oxygen cannot be used as target value. As for the devices before, a detailed consulting is necessary for correct application. Please contact us per e-mail.
EC-Module
Inexpensive oxygen measuring device based on aqueous electrolyte systems. It is mainly used for the oxygen detection in the percent range. For further information contact us by e-mail please.
Hydrogen Sensor TCS
The hydrogen sensor TCS (thermal conductivity sensor) is a compact measuring device, which is directly mounted on the measuring chamber by vacuum components. The sensor is pre-thermostatted by its own electronics, whereby a very high stable sensor signal is ensured. Originally developed for nitriding equipment of contract heat treatment workshops, the sensor is applicable for special measuring problems (e.g. low pressure application) due to a sophisticated calibration method.
In many technological processes, hydrogen plays a big role in achieving the desired product properties. By means of TCS, the hydrogen concentrations can be analyzed and provided to the process control via standard interfaces.
Due to the increasing adoption of quality management systems (e.g., ISO 9001), a constant monitoring and documentation of measured values is necessary.
With the TCS, the user can monitor hydrogen measurement efficiently and continuously.
