Hot wire rapid thermal conductivity meter/QTM-500 thermal conductivity meter

Hot wire rapid thermal conductivity meter/QTM-500 thermal conductivity meter Main features:

1. Quickly and easily measure the thermal conductivity (thermal conductivity) of various types of samples.
2. Depending on the type of sample and temperature measurement, appropriate sensors (probes) can be selected.
3. LCD display, which can directly observe the temperature rise curve during measurement.
4. The heating curve is displayed in logarithmic time, which confirms the linear value of the measured value.
5. Automatically determine the appropriate heating current value for the sample (applicable only to PD-11).
6. After automatically determining that the sample temperature is stable, proceed with the measurement.
7. Can measure thin film or paper samples (optional items need to be purchased separately).
