Other Details

DIGITECH Thermal Conductivity Apparatus, Model - 8050 PTH, is a microprocessor based instrument designed to measure and display the thermal conductivity of insulating materials, using guarded hot plate method as per guidelines of latest Indian Standards: IS-3346/ASTM177. The instrument is automatic and programmable; designed with latest integrated circuit technology. The instrument displays the “K” value directly in engineering units. The samples of the material to be tested are placed on either side of a horizontal guarded hot plate, consisting of a central heater surrounded by a separately controlled guard heater.Two auxiliary heater plates are provided on the other side of the two samples to produce a uniform and constant temperature on the other side of the sample. Two fluid cooled cold plates are also provided to work on a low mean temperature. Fluid temperature control may be done externally. The guard and central plate heaters are fed through high performance, regulated D. C. power supplies, controlled by differential temperature controller. The auxiliary heater plates are controlled by S. C. R. proportional temperature controller. Temperature measurement is done by embedded thermocouples in guarded hot and auxiliary plates. Window based software is provided, to display temperature of thermocouples and power fed to central heater. K-Value is automatically calculated and displayed as per sample parameters and temperature data. SPECIFICATIONS Mean Temperature Range : 100 to 550 deg.C Measurement Range : 0 to 1.0 Watt/mK. Accuracy : +/- 5%. Sample Thickness : 25 to 50 mm.
