The G4 PHOENIX DH has been developed for the determination of the diffusible hydrogen in different sample matrices. The analysis system comprises a rapid heating infrared clamshell furnace and/or a wire-heated tube furnace, both equipped with a quartz tube for heating of the sample. The diameter of the tube in the infrared furnace is 30 mm so that even big samples like weld seams according to EN/ISO 3690 and AWS A4.3 can be analyzed without problems.

A simple and reliable calibration is guaranteed by the integrated automatic gas dosing unit with 10 different volumes. The heart of the analyzer is a highly sensitive and long term stable thermal conductivity detector for reading even smallest hydrogen contents.

The Application

The G4 PHOENIX DH is suitable for the automatic determination of the diffusible Hydrogen content in solid material, like steel, aluminum, welding materials, weld seams etc.

The Software

The analysis software of the G4 PHOENIX DH is clear and simply structured. All tasks to be performed by the software are clearly divided into four different screens.

The Benefits

  • Temperature programmable infrared furnace, temp. up to 900°C, rapid heating and cooling, tube diameter 30 mm, e.g. for welding samples according to EN/ISO 3690 and AWS A4.3
