HAMPTON, VA.  DECEMBER 2, 2010 -Teledyne Technologies Inc., Hastings Instruments (THI) has completed a comparison study of thermocouple vacuum gauge tubes available from the top manufacturers.  New gauge tubes from the various manufacturers (minimum quantity of five per supplier) were procured for testing.  THI has thoroughly reviewed these tubes and has prepared the "inside story".  The illuminating results can be seen on a special website, 

The study includes tube-to-tube measurement repeatability, vibration table results (Mil-Std-202, Test Condition IG), and construction method analysis.  The special website features an automated slideshow and includes comparably scaled photos and tables.  Visitors can see the presentation and download the results for themselves.            

James M. Camper, Vice-President of Teledyne Hastings Instruments, stated "Hastings Instruments produces reliable vacuum products engineered with customer expectations, and the integrity of their processes, foremost in our designs. With inferior copies of our established products entering the market it is time to benchmark Hastings' superior designs and fabrication techniques. This study yields many interesting engineering contrasts and confirms Hastings Instruments' vacuum gauge tubes are unsurpassed in quality."

THI, an ISO 9001:2008 certified manufacturer, produces a complete line of instruments for precise measurement and control of vacuum, pressure, and gas flow.
