This low cost, single temperature test instrument is used for quick determination of thermal conductivity of solid materials. Because of its simple operation, small sample size, and short cycle time, the QuickLine™-10 is ideally suited for quality control and screening of materials. Metals, ceramics, polymers, composites, glass, and rubber can be tested accurately. Thin samples like paper products and plastic films can also be tested.
QUICKLINE™-10 TEST METHOD
A test sample is held under a compressive load between two polished metal surfaces. The upper surface is temperature controlled. The lower surface is part of a calibrated heat flux transducer, which is attached to a liquid cooled heat sink. An axial temperature gradient is established through the stack as heat flows from the upper surface through the test sample to the heat sink.
After reaching thermal equilibrium, the temperature difference across the sample is measured along with the output from the heat flux transducer. These values and the sample thickness are then used to calculate thermal conductivity. The temperature drop through the sample is determined from temperature sensors in the metal surfaces on either side of the sample. The QuickLine™-10 is factory calibrated using samples of known thermal resistance spanning the range of the instrument. Calibration reference sets are available. The contact resistance is kept small by applying a reproducible, pneumatic load to the test stack. |

The QuickLine™-10 test method is in accordance with specification ASTM E1530 for measuring thermal conductivity. The unit is supplied with a utility software program for convenient data analysis using a PC. The user simply enters data from the QuickLine™-10 digital display via the computer keyboard and the thermal conductivity is automatically computed. If the measured thermal resistance value falls outside the range of the instrument, the program suggests testing a different sample thickness for obtaining more accurate test results. If a PC is not available, data analysis can also be carried out manually following instructions from the user's manual.
The instrument is completely self contained and requires no additional instrumentation for the measurement. When city water is used for cooling, the mean sample temperature may vary slightly as the water temperature changes with the seasons. If this variation is undesirable, an optional chiller providing coolant at a fixed temperature can be connected to the unit instead. The QuickLine™-10 is a simple, fast, accurate, and reasonably priced laboratory instrument.
