Thermal Conductivity Apparatus

 

A Flexible Instrument for Thermal Conductivity Experiments

The LB-EPM Thermal Conductivity Measuring Instrument for Good Conductors uses a replaceable sample design. You can easily change the experimental sample for different tests. The experiment method is the electrical work method. The instrument uses air cooling for heat dissipation. You do not need a water tank or water pump. This makes the setup very simple. A 24V DC heater provides the heat source. PID temperature control keeps the temperature stable. The temperature control accuracy is ±0.1°C. Two temperature measurement modules are included. Each has a temperature accuracy of ±0.1°C. The Thermal Conductivity Apparatus for Good Conductors helps students understand how heat moves through solid materials. It gives accurate and repeatable results.

The LB-EPM Thermal Conductivity Measuring Instrument for Good Conductors has a special electrical work measurement module. This module can measure electrical work automatically at a set time. The timing period is freely adjustable. The adjustment range is 10 to 360 seconds. The step value is 5 seconds. You can switch the display between the measurement time progress and the real-time electrical work value. The electrical work measurement range is 0 to 99,999 W·S (Joules). This module makes it easy to calculate the amount of heat generated by the heater. Students can directly compare the electrical energy input to the heat transferred through the sample. This gives a clear understanding of thermal conductivity.

The air cooling design removes the need for any water connections. The Thermal Conductivity Apparatus for Good Conductors is safe and clean to use. The replaceable sample design allows the same instrument to test different materials. The PID controller keeps the temperature stable without manual adjustments. Two temperature sensors measure the temperature difference across the sample. The electrical work meter provides accurate energy readings. This instrument is ideal for undergraduate physics and materials science labs. Students learn how to measure thermal conductivity using a steady-state method with electrical heating.
