ESFJ series helium mass spectrometer leak detector

Product introduce:

ESFJ series helium mass spectrometer leak detector is learn from foreign advanced leak detection technology and our own design experience. The key components are imported, it has stable and reliable performance. It not only has high sensitivity, but also has the advantages of convenient operation, auto switching of two filaments, auto-zero, auto calibration, and auto range switching, it already reaching the international advanced level at present.

Performance characteristics:

Easy operate,only two key buttons(Leak detection and degassing)to be operate

Multi-port molecular pump from Germany

Dual filaments,auto switch from one to another

Auto-zero auto calibration

Auto range switching

Valve detection with PPM function

Full-automatic control, colour touch screen,powerful

Major dispositions:

Compound molecular pump of Germany Leybold

Mechanical pump (D16C) of Germany Leybold

Molecular pump of Germany Pfeiffer

Mechanical pump of Ulvac

Electromagnetic valve of Germany Burkert

Imported amplifier

Standard leak hole (Including calibration certificate)
