Instrument Features

1. High sensitivity transducers: A revolutionary high output Thin Film Heat Flux Transducer is permanently bonded to each plate. A type E thermocouple is bonded in the center of each transducer and both are sealed to insure consistent precision over time. Because each is within 0.1mm (0.005") of the sample's surface they provide accurate readings of the sample's surface temperature and heat flux.
2. Advanced electronics: A 24 bit analog to digital converter and a digital signal processor provide 0.6猩 resolution yielding temperature control and resolution of 0.01蚓.
3. Accurate thickness measurement: A sophisticated digital plate position control system with readout in all four corners of the specimen provide +/-0.025mm (0.001") accuracy in thickness measurement.
4. Precise results: Extensive testing at various locations including Oak Ridge National Laboratories has shown that FOX Instruments have a repeatability of 0.2%, a reproducibility of 0.5%, and when the high accuracy calibration mode is used an absolute accuracy of better than 1%.
5. Time of tests: Thanks to the powerful data acquisition system, the unique low thermal mass design of the solid state cooling/heating plates and the sophisticated multistage PID algorithm typical testing temperatures can be reached and controlled to 0.01蚓 in a few minutes. The dual transducers and advanced electronics provide results for 1" thick specimens accurate to within 1% of final steady state results in less than 10 minutes.
6. Calibration: Two modes are provided. One calibration uses the NIST 1450b standard recognized throughout the world. The other employs a special high accuracy NIST traceable calibration standard accurate to within 0.5%. Calibrations can also be performed by the user employing their own calibration samples. As many calibrations as desired can be stored on the computer and sent to the instrument at any time.
7. WinTherm Software: Increased flexibility is made available through the software used under Windows. Through a series of windows all the test parameters can be setup and changed at any time during the test, with the ability to review data from previous and or current tests in a variety of formats including graphs. It also provides extensive automatic data storage on the hard disk and the ability to run up to 8 instruments simultaneously on one host computer. A printer can be connected directly to the instrument and results printed.
8. Size and weight: Our instruments are a fraction of the size and weight of prior thermal conductivity instruments and their modular design simplifies their very rare need for service.
9. Automatic Sample Feeder: is available on FOX200s, FOX300s and FOX314s with the ability to automatically load and test 21 1" samples. Each sample's results and data are stored on the computer.
10. Prices: The Instruments are extremly cost effective. For more information contact: Kevin Collins, Sales and Marketing Manager.
