Test Procedures
First: Prepare the accessories and test samples;
Open the instrument's test chamber;
Place the sample inside the chamber;
Close and lock the test chamber lid;
Measure the sample thickness using a depth gauge;
Open the positioning rod on the side of the chamber and flip it over;
Release the positioning rod;
Place another sample inside this chamber (the instrument has two identical heating units);
Turn on the low-temperature bath and power switch;
Pour in a certain amount of water;
Turn on the instrument and access the LCD screen operating interface;
Set the hot plate temperature, sample thickness, preheating time, and test time, etc.;
Click "Start";
The system forms a thermal cycle, and the sample is tested;
When the set time is reached, the instrument automatically stops. Open the chamber and remove the sample;
The test is complete. Turn off the instrument;
Analyze and compare the test data to evaluate the material's thermal conductivity.
