Hydris® - Measuring System for Quick Determination of Hydrogen

The Hydris® probe is immersed into the steel melt by means of a manual or automatic immersion lance.

• A pneumatic cable links the Hydris® lance with the Hydris® pneumatic unit.
• The Hydris® pneumatic unit conveys a carrier gas through the Hydris® pneumatic lance and attached Hydris® probe into the steel melt. Here, the gas absorbs the hydrogen contained in the steel melt.
• The carrier gas is continuously circulated through the measuring system until a Sieverts’ equilibrium is reached between the hydrogen content in the steel melt and the carrier gas.
• The hydrogen content is measured and displayed as the result, when the equilibrium has been reached.
