Fison Thermal Conductivity Tester measures thermal conductivity in solid materials from 0.010–5.000 W/(m·K), with measurement accuracy better than 3%. Microprocessor-controlled temperature regulation maintains test conditions, while the LCD displays hot plate and cooling plate temperatures during measurement. Manufactured for assessing insulation performance in foam, rubber, plastics, and other materials in testing laboratories and construction industries, this Thermal Conductivity Measurement Instrument supports material testing.
