Ideal for measuring the thermal conductivity of plastic materials with maximum dimensions 300 mm x 300 mm.
The thermal conductivity is measured by placing the specimen between plates with two different temperatures.
The Heat Flow (F) and the thermal exchange coefficient (U) are shown on the display at the end of the test.
The maximum measurement values are: F=19,999.99 W/m2 and U=19.999 W/(m2K).
Working temperatures: -40°C to +90°C.
Optional equipment includes digital cyrostatic baths and certified reference samples.
Meets ISO and equivalent national standards.

It consists of a module, thermically insulated, inside which two radiant elements are housed, both suitable to reach different pre-set temperature values. The lower one is kept at a lower temperature as regards the upper one through an outside thermostatic unit. On same the thermic flow measurement probe is housed. Inside the probe there is also a sensor of superficial Tp, temperature of the lower side of the specimen. The upper one, kept at a higher temperature than the lower one by a separate outside thermostatic unit, houses the sensor of superficial temperature Tg of the upper side of the specimen.

This second radiant element is moreover adjustable height-wise to allow insertion of specimens of different thickness and is connected to a position sensor capable to visualize on a separate display the specimen thickness when in testing conditions with a 0.1 mm accuracy.
