DH603-G4 diffusion hydrogen analyzer

Instrument Introduction

DH603-G4 diffusion hydrogen analyzerWidely used in fields such as steel, shipbuilding, pipeline, bridge design, military industry, and university research, it is mainly used for research and control of hydrogen embrittlement hazards such as failure analysis, process development, and quality control of various metal materials, as well as analysis of diffusion hydrogen content and thermal desorption rate of welding materials, cladding metals, and steel.

DH603-G4 diffusion hydrogen analyzerEquipped with a fast heating infrared furnace and used for sample heating in a quartz tube with a diameter of up to 30 mm, to achieve analysis of large samples. The sample undergoes high-temperature thermal extraction of H in inert gas to generate H₂The diffusion hydrogen content and desorption rate were measured by a high-sensitivity detector. The fully automatic gas calibration system can be calibrated with pure hydrogen or pure helium gas. For the detection of ultra-low diffusion hydrogen in high-strength steel, it complies with domestic and foreign standards such as ISO 3690, AWS A4.3, GB/T 3965-2012.
