va-Q-check

   
       
 

The worldwide patented va-Q-check is unique control system for VIPs. It makes a control of VIPs possible during production & installation.

• Measure time : ca. 5 - 10 sec./VIP
• Direct contact with VIP is necessary
• Sensor und barcode-label
• Possible measurement ranges from 0.02 to 10 mbar,
  in particular applications up to 100 mbar

Advantage of quality control by va-Q-check
• 100% production control of VIP´s inner gas pressure
• Easy, fast and accurate measurement
• Check of vacuum by customer possible
• Life time assessment by repeated measurements
• Accuracy (repeatability) as low as 10% possible

Principle of va-Q-check
• An external sensor device generates a heat pulse
• The heat flux through the covering film and the multi layer sensor
   is measured
• The heat flux depends on the internal gas pressure
