Leybold LDS1000 Leak Detection System

1 x Used Leybold LDS1000 Modular Leak Detection System for Integration in Leak Testing Systems

Modular concept for flexible system design.

The LDS1000 is a helium leak detector for universal integration in industrial leak testing systems (vacuum or sniffer mode). The modular design concept allows the cost effective and flexible integration into systems for various applications.



Smallest detectable helium leak rate:
FINE mode       mbar x l x s-1    < 5 x 10-11
GROSS mode    mbar x l x s-1    <3.5 x 10-10
Sniffer mode     mbar x l x s-1   <1 x 10-7



  • Fast response time for short testing cycles.
  • Measurement of the true leak rate of the test sample while simultaneously pumping down the test chamber (partial flow operation).
  • Easy to operate.
  • Switching over from vacuum leak detection to sniffer leak detection upon a single key press allows for immediate pin-pointing of the leak during the same test step.
  • Control and acquisition of data via programmable control compatible signals or RS232 interface.
  • Control and data acquisition software LDS-WARE (optional).
  • Chart recorder output 0-10V lin/log for logging the leak rate and the fore vacuum pressure.
  • Calibration through internal calibrated leak.  Additionally calibrations with external test leaks (master testers) or dynamic calibrations are possible.
  • Electronics module prepared for mounting in a 19" rack, offering protection against dust, high temperatures or electromagnetic interference.
  • The operating unit may also be detached from the instrument and been used in any position.
