MMC offers a wide range of different measurement probes, samplers and instruments for liquid steel applications.
The Hydris sensor system uses the principle of hydrogen partial pressure distribution between gas and liquid phase. The Hydris system gets a certified gas composition into equilibrium with the liquid metal to be measured. Using Sieverts’ law the hydrogen concentration in liquid metal may be calculated. The Hydris system does this automatically. Immersion of probe and reading are very much like a temperature test, just the immersion time of the probe is a little longer, but typically less than a minute. Hydris’ precision is today the industrial standard of hydrogen measurement in liquid metals, operator ind
ependent and free from previous sample preparation and analysis errors. A reported Hydris certificate is worldwide accepted as best method.
Depending on application different sensor types are used:
