Usage
The hydrogen analyzer, which works on the Straube-Preiffer test principle (decompression solidification test method), is used to qualitatively measure the content of hydrogen in molten aluminum. A decompression solidification test is conducted to make a solidification sample of molten aluminum under the conditions of decompression (a vacuum degree determined according to the technological requirements). Subsequently, the sample is analyzed by various methods to qualitatively determine the content of hydrogen in molten aluminum in an indirect way. It can be used for quality control during aluminum alloy casting and for smelting detection.

Equipment Features
  High analysis speed. In the field environment, it just takes 5 minutes to analyze the content of hydrogen in molten aluminum.
  The test results are true and reliable, with high repeatability. Several analysis methods can be used together to accurately judge the quality of molten aluminum to provide reliable guidance on production.
  Easy and safe to use. Operators neednâ??t have rich experience and can use it correctly after training.
Made of aluminum alloy, the vacuum chamber is light, easy to handle and resistant to corrosion.
