LAMBDA System 1: Ambient-45°C to +400°C

LAMBDA System 1: Thermal conductivity of fluids, up to +400°C.
LAMBDA System 1: Thermal conductivity of fluids, up to +400°C.

The LAMBDA System measures the thermal conductivity of fluids according to ASTM D 2717. It is also very suitable to measure the thermal conductivity of fluids and dispersions with nano particles (nanofluids).

The temperature control by special heating thermostats provides a homogeneous temperature distribution, which is indispensable for accurate measurements.

Further Characteristics:

  • Thermostats for temperatures up to +190°C and +400°C available
  • Temperature ramps and sweeps possible
  • Measurements under pressure and inert gas flushing possible
  • Windows software for control and data visualisation

Applications:

  • Optimization of fluid application and development
  • Quality control
  • Nanofluids
