QTM-710/QTM-700 can measure thermal conductivity of uniform material easily in a short time.
The thermal conductivity of various samples such as block form or sheet in manufacturing, construction, handcraft, soil or food industry is possible to measure by placing a probe on the surface of sample with the uniform temperature.
- Thermal insulating material of fiber or foamed plastic
- Plastic, Glass, Wood, etc.
- Sheet, Leather, etc.
- Bread dough, Mashed food, Powder, etc.
- High heat insulation material, Ceramics, etc.
Features
- Clear and easy operation with the touch-screen of 5.7 inch color LCD
Intuitive operation is possible with touch-screen. - Quick measurement with 3ch probes
By connecting the multiple probes (the same type or other type), the equipment can measure samples in series without changing the probes, less waiting time. - Easy data transfer with a USB flash drive
Measurement data transfer to personal computer is easy with a USB flash drive.
Data is viewable and editable in the spreadsheet software because it is saved in CSV format. - Security function
Password setting and security level can be selected in accordance with the intended use and the environment. - Probe is compliant with traceability.
Traceability system of the thermal conductivity standard substance (reference plate) is established for the purpose of further improvement of the reliability of the measured values - Built-in Thin film measurement (QTM-710)
Thermal conductivity of the sheet sample such as a film and a sheet of fiber products can be measured.
It is easy to analyze the result since the average and the standard deviation of measurement results are calculated and the rise temperature graph is shown.
