The TLS-100 is a portable meter used to measure thermal conductivity and thermal resistivity of a variety of samples, including soil, rocks, concrete and polymers. Tests are performed with the push of a button and results are displayed instantly. The TLS-100 features sensors that are auto-recognized with corresponding testing parameters automatically loaded.
The TLS-100 follows ASTM D5334-22a and IEEE 442-2017. The sensor needle consists of a thin heating wire and temperature sensor sealed in a 150, 100 or 50 mm steel tube. The sensor is completely inserted into the sample to be tested. Heat is delivered to the sample using a constant current source (q) and the temperature rise is recorded over a defined period of time. The slope (a) from plot of temperature rise versus logarithm of time is used in the calculation of thermal conductivity (k). The higher the thermal conductivity of a sample, the lower the slope. For samples of low thermal conductivity, the slope will be higher.
The TLS 100 includes:
- Controller for running tests, viewing and exporting results.
- 100mm needle for use in soils, pastes, powders and solids
- Weather resistant carrying case
- Nylon verification sample
- Contact paste
- Drill bits (x2) and needles sleeves (x3)
- Manual
- 1year limited warranty for meter
- 30day limited warranty for needle
