|The FOX200 instrument can be used to measure apparent thermal conductivity of thermal insulation materials. It was designed according to the ASTM C518-04 “Standard Test Method for Steady – State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus”.||
The instrument is calibrated using the NIST SRM 1450b (Standard Reference Material of the National Institute of Standards and Technology, and the special high accuracy (0.5%) EPS (Expanded Polystyrene) NIST Standard. The calibrations were done with a 25 oC ή 20 oC temperature difference and are saved in instrument’s memory.
Thermal conductivity range 0.01 – 0.02 W m-1 K-1
Maximum temperature of hot plate 75 oC
Minimum temperature of cold plate -20 oC
Temperature control stability ±0.03 oC
Thickness measurement accuracy ±0.025mm
Maximum sample size 203 x 203mm

Interaction with pc and printer RS-232 serial interface
Wintherm 32 Software for connection the FOX200 to a PC
The software can manage the operation of the instrument from a PC, record the results in a file and can be programmed to execute experiments in a big range of temperatures for the same sample.
