* * * varian 947D helium leak detector * * * vacuum

A high sensitivity, high speed leak detector offering the end user optimal cleanliness and sensitivity.
* Factory trained service personnel have recently overhauled Leak Detector, including complete dis-assembly and cleaning , re-assembly with New O-rings and New Ion-Source. Fully tested and ready for immediate use.
* Forepump and roughpump are Iwata 600DS with less than 800 hours. Pumps have been bench tested with a base pressure of less than 25 mT.
* Vacuum System Arrangement:
* V70 Turbo Pump Pumping Speed (N2):
* 2 x 10-10 atm cc/sec (helium)
* Less than two seconds for helium
* A 50-segment bar graph indicator displays leak rates from
10 to 1 x 10-10 atm cc/sec automatically. The manual mode can be
used for any decade scale. A leak can also trigger an audible alarm
whose frequency varies in proportion to the size of the leak.
* 11/8 (28mm) ID quick coupling type
