FOX50

Dimensions:

Depth: 26.7cm (10.5")
Height: 28cm (11")
Width: 16.5cm (6.5")

LaserComp offers the Fox50 in three temperature ranges:

Fox50     0°C to 110°C¹  

Fox50 ~50°C to 190°C¹ ²  

Fox50 ~80°C to 300°C¹ ²

¹Instrument can reach temperatures ~20°C lower when using a Neslab M 25 chiller.

²Lower temperature depends on thickness and conductivity of sample.

The FOX50 series are microprocessor based instruments for testing in accordance with ASTM C 518 and ISO 8301. They are designed for testing the thermal conductivity of materials in the conductivity range of 0.1W/mK to 10W/mK. The instruments are designed to test polymers, composite materials, low conductivity ceramics and glasses. They test up to 63 mm diameter specimens from 0 to 25 mm thick (2.5" diameter 0 to 1" thick), but can open to 26.27 mm (1.05") for easy sample removal. The actual metering area is 25 mm (1") square.

Specimens can be tested repeatedly at any one temperature within this range. Alternatively, up to nine temperatures can be entered for each specimen in which case the instrument will automatically advance to the next temperature once equilibrium conditions have been established. At the end of each test the results are displayed (or printed if an RS 232 printer is attached).

A set of two pyrex standards of different thickness are provided in order to verify the Two Thickness procedure which eliminates air interface from results.

Cells for molten sample and liquid testing are available.

The specimen thickness is continuously monitored during the test by a sophisticated digital thickness readout system. Standard resolution of thickness readout is better than +/-0.0254mm (+/-0.001"). Constant pressure between the plates and the sample is provided through a pneumatic cylinder. Both plates of the instrument are equipped with thin film high output heat flux transducers developed and manufactured by LaserComp.

Upper plate can adapt itself slightly to non parallel sample surfaces to obtain better contact with both plates.

The use of two heat flux transducers accelerates the tests and produces more accurate results.

FOX50 utilizes state of the art analog and digital electronics developed specifically for thermal conductivity testing instruments. The accuracy of the temperature control is +/-0.01°C. External thermocouples can be connected to outlets in back. The heat flux transducer readings are resolved down to 0.6 micro volts.

The FOX50 is also very simple to operate. Step by step instructions are displayed on a clear four line LCD display. The instrument can easily be operated by an operator with minimum training. Each instrument is equipped with an RS232 port. The port is used to print results or to connect the instrument to a host computer. Input power can be either 115V or 220V 50/60Hz user switchable at 300VA (350VA for the 300°C version). Water at 18°C (65°F) or lower and air at up to 90 PSI (low consumption) are also required.
