The RH-404 System is a microprocessor-based instrument for measuring hydrogen content in iron, steel, and other ferrous and nonferrous materials. The RH-404 System is comprised of the RH-404 Determinator and either the EF-400 Electrode Fumace or the EF-500 Electrode Fumace with an automatic cleaning mechanism. The system includes a built-in balance, an electroluminescent display, printer, and kyboard. Samples can be introduced in solid, milling, or powder form. Total analysis time for hydrogen, measured in parts per million (ppm), is 31/2 minutes, including 60 seconds for crucible degassing.
