Thermal Conductivity Portable Meter Customer Comment TLS-100 Icon

TLS-100

The portable transient line source TLS-100, designed with ease of use and convenience in mind, is capable of testing soils, rocks, concrete and polymers for thermal conductivity and thermal resistivity.
ASTM D5334 & D5930, & IEEE 442-1981
0.1 to 5 W/mK

Portable Thermal Conductivity Meter THW-L2

THW-L2

The transient hot wire THW-L2 is well known for high accuracy thermal conductivity measurements of liquids and pastes. Measurements may be performed with a simple push of a button or with the included Windows software.
ASTM D7896
0.01 to 2 W/mK

Portable Thermal Conductivity Meter TPS M1

TPS M1

The TPS M1 is designed for measuring the thermal conductivity, thermal diffusivity, specific heat and thermal effusivity for solids, pastes and powders, which are low to mid-range thermal conductivity materials, like foam insulation, rock and concrete. Measurements may be made in single-sided or two-sided TPS sensors.
ASTM & ISO
0.03 to 40 W/mK
