FAQs about Pfeiffer Series Built-in Leaks

1、How to determine if built-in leak needs replacement?
Consider replacement when calibration deviation exceeds ±15% or response time significantly prolongs.

2、How to compensate temperature drift?
Recommend standard operation at 23±2℃. Recalibration needed for every 10℃ temperature change.

3、Does it support non-helium detection?
Customization available for Ar, N2 etc., but gas type must be specified in advance.

4、How to adapt interfaces for different helium detectors?
Provides standard interface customization for Pfeiffer/Varian/Agilent etc.

5、How to control annual loss rate?
Recommend annual CNAS certification calibration to establish loss curve.

6、Advantages of microchannel capillary technology?
Better contamination resistance and stability compared to traditional sintered leaks.

7、What if charging pressure exceeds range?
May cause nonlinear leak rate change or even capillary structure damage.

8、Can leaks be repaired on-site?
Capillary components cannot be repaired, recommend direct standard module replacement.

9、How to verify leak accuracy?
Requires cross-verification using standard leak comparison device.

10、Lead time for customized leak rates?
3 workdays for standard models, 7-15 workdays for special leak rates.
