Helium Modular Leak Detector INFICON LDS3000


94 lượt xem



The Helium Modular Leak Detector INFICON LDS3000 is the updated version of the LDS2010. The instrument has set new standards for accuracy, reproducibility of measurement results and speed of leak testing.

The LDS3000 is designed with extremely small dimensions, 330 X 240 X 280 mm (13 X 9.45 X 11.1 inch). It makes the instrument become easier to be integrated into leak testing systems. Moreover, the space requirements and installation costs have been reduced even further, by eliminating the 19″ control module and significantly improving the cabling.

The Helium Modular Leak Detector LDS3000 is also available as LDS3000 AQ for the use in accumulation systems. The LDS3000 product family is the most appropriate solution for automated testing sytems.


  • Fast, optimized response times with I·CAL technology
  • Compact design allows individualized, custom integration into leak detection systems
  • The new, patented routine allows calibration of the LDS3000 leak detector within 20 seconds.
  • Communicative diversity through a wide range of analog and digital interfaces
  • Considerably improved cabling
  • LDS2010 compatibility model


  • More Compact And Easier To Integrate
  • Communicative Diversity
  • High Reliability
