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 near 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
quality control by va-Q-check
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
