VIC MS50HS Console Helium Leak Detector 120V 1P

Current Stock:

Product Description

Manufacturer: Vacuum Instrument Company

Model: MS50HS

Condition: Used. Very nice with wear consistent with age The photos show the exact item(s) the buyer will receive.

Notes: We fired up this leak detector.  The foreline pump achieves 6mT into a vacuum gauge.  The rough pump achieves 8mT into blank test port. Both test port and foreline gauges were calibrated.  There is no detectable He background.  Paint loss at front edge of console was corrected.  Cabinet air filters were cleaned.  Pump oil was changed; the oil is TW (technical white.)  Autotune runs successfully.  The internal calibrated leak has not been refilled or calibrated in ten years; we made allowance for this and reset the leak rate in settings.  If your application requires a calibrated leak then you will need to send it in for calibration.  Hivac was 7E-5 Torr. 

There is an LN2 reservoir on this leak detector.  Its use is not mandatory as it is on diffusion-pumped systems. 

Here is a very nice leak detector ready to work. No manuals, cords/cables, or additional items are included if not listed or shown.
