Fox Series Heat Flow Meters are reliable, easy-to-use, and durable thermal conductivity measurement instruments. Each of our FOX heat flow meters combines advanced technology with over 20 years of superior engineering. Explore our lineup of thermal conductivity instruments.
The thermal conductivity of a specimen is determined by measuring the heat flux, specimen thickness, and temperature difference across the specimen. In each component of the thermal conductivity equation, FOX Instruments provide extremely precise readings: 0.6 mV resolution on integrating high output heat flux transducers, 0.001” precision in thickness measurement, and 0.01°C temperature control and resolution. Each of these individual measurements is an order of magnitude more accurate than any other competitive thermal conductivity instrument. These measurements combine to provide the most accurate results of any heat flow meter currently available. When using the high accuracy calibration standard mode, FOX Instruments challenge and exceed the accuracy of the expensive, enormously time consuming, and operator dependent, Guarded Hot Plate instruments.
