External Test Circuit

External Test Circuit for Installation in Test Machines

Many users of our test equipment want to physically separate the test specimen adaptation from the measurement and control electronics.
In many applications, this offers advantages in terms of installation space and measurement accuracy.
The INTEGRA evo can also meet this need.
  • Compact external test circuit
  • Measurement taken directly at the scene
  • Unnecessary residual volume is avoided
  • The measurements are faster and more accurate
  • Operation via the INTEGRA evo main unit
  • Available for relative pressure or differential pressure measurement
LTS_compact_dis

LTS Compact

Compact, simple. Cost-effective

  • Cost-effective single-purpose leak testing device for relative pressure testing
  • Available for overpressure or vacuum
  • Adjustable limits
  • Proven microelectronics
  • Sophisticated test pneumatics
  • Compact dimensions
  • RS232 as standard
  • Optional digital I/O interface

All devices are characterized by high measurement resolution, robust technology, and versatile interfaces. They are delivered with factory calibration and include a test certificate according to DIN EN 10204. Custom solutions for special applications are also possible.

The product range is complemented by practical accessories – such as calibration units, vacuum generators, or remote controls. Our application engineers will be happy to assist you with the planning and parameterization of your individual solution.
