Hydrogen content Analyzer

Hydrogen analysis content device in molten aluminum. New series optimized for use with ultrasonic degassing!

The hydrogen detection analyser in molten Aluminium detects the hydrogen content in aluminium foundries and casting industries, as high residual hydrogen can result in significant porosity after casting, leading to rejections or the risk of mechanical failure.

Our new hydrogen detection analyser is the solution for your foundry to effectively and rapidly measure the hydrogen content in aluminium melts. It is the best option also during ultrasonic degassing and ultrasonic grain refinement of molten aluminum.

Why is the Hydrogen detection analyser important in an aluminium foundry or cast house?
Hydrogen forms whenever molten aluminium comes into contact with water vapour, and easily dissolves into the melt. The gas tends to come out of the solution and forms bubbles when the melt solidifies.
The detrimental effects arising from the presence of an excess of dissolved hydrogen in aluminium are numerous.

Hydrogen causes porosity in aluminium products leading to many casting defects, reduced mechanical properties like fatigue and lower corrosion resistance. Several methods are used to reduce the amount of dissolved hydrogen from the melt, such as furnace fluxing prior to the casting process or using in-line degassing equipment during the casting process.

Info H-Test Analyser

The new H-Test Analyzer (HTA) makes it easier to substantially improve both – the Quality and the Reliability of your Aluminum castings, by enabling you to precisely control the Hydrogen content in the Aluminum melt just before casting. No under or over degassing. No rejections, no wastage of time or money.

  • HTA uses the reduced pressure technique to measure the H2 content. By controlled solidification, the partial pressure of all the H2 released is accurately measured and related to its percentage by HTA.
  • HTA gives you accurate quantitative information within 3 minutes of sampling, for you to optimize the level of degassing.HTA comes to you with a quality assurance from the trusted house of Nico van Dongen Consulting Ltd.
