THERMAL CONDUCTIVITY AND HEAT CAPACITY METER FOR LIQUIDS ITS-λc-20

SKU0067
DESCRIPTION

This automated device is designed to determine the thermal conductivity λ and specific isobaric heat capacity c of liquid petroleum products and polymer solutions under normal conditions. The device includes a thermal measurement cell, a specialized thermophysical controller TFK-2.2, and a set of metallic ampoules with through concentric holes. 

CHARACTERISTICS

  • Measurement Range:
Thermal conductivity λ: (0.10...0.70) W/m×K.
Specific heat capacity c: (2.0...4.2) kJ/kg×K.
  • Temperature Range for Measurement: (25 ± 5) °C.
  • Dimensions: Fits on a laboratory table with an area of 0.5 m^2.
  • Experiment Duration: 3 to 30 minutes (depending on sample properties).
  • Measurement Accuracy:
Specific heat capacity: ± (5–7)%.
Thermal conductivity: ± (7–10)%.
  • Power Supply: 220 V, power consumption up to 300 W.
  • Sample Dimensions and Shape: Samples are filled into specially designed metallic ampoules with concentric holes.

Controller TFK-2.2 Capabilities:
  • Input of initial experiment parameters.
  • Measurement of temperature sensor readings across eight independent channels (thermocouples, micro-thermistors, resistance thermometers).
  • Control of a heating element connected to the controller.
  • Maintenance and control of heating power at a specified level.
  • Conversion of electrical signals from sensors into the temperature gradient of the sample relative to the isothermal block.
  • Graphical display of sensor readings during the experiment.
  • Storage of experimental data for one experiment in the internal memory.
  • Data transfer to a PC via RS-232 and Ethernet interfaces.
