ASTM C518 Thermal Conductivity Tester for Foam Rockwool and Insulation Board. Automatic Computer Control The system integrates automatic temperature control, specimen clamping, pressure loading, thickness measurement, data collection, calculation, and test report generation. Stable Hot Plate Temperature Control The hot plate uses a precision programmable temperature controller with a standard operating range from room temperature to 100 C. Stable heating conditions impro. Precision Cold Plate Cooling System The cold plate is connected to an adjustable constant-temperature water circulation unit. The standard cold-side temperature range is from 5 to 90 C. Automatic Specimen Clamping Computer-controlled clamping applies consistent pressure to the specimen. This design improves contact between the specimen and measuring plates and helps reduce measureme.
