    DRH300 series thermal conductivity meter is based on the steady-state method, is able to measure 30 cm x 30 cm samples, thickness ranging from a few millimeters to 10cm. All testing functions automatically; Motor control of the plate movement; Measurement set up and run very fast; Sample sandwiched between two heat flux sensor test, fixed or adjustable temperature gradient. In a few minutes after stability of temperature and temperature gradient, using the embedded controller or external computer measured the thermal conductivity (K), thermal conductance (C) and thermal resistance (R) of the sample. Automatic upper plate move and sample thickness measurement, simplifies the test preparation. All test parameters and the correction data can be stored in the computer. It is suitable for industrial applications, superior performance. DRH300 coefficient of thermal conductivity measurements conform to ASTM C 518,ISO 8301, JIS b 1412, DIN EN 12939, DIN EN 13163 with DIN EN 12667 and relevant international standards.     Product list:        DRH-300D Testing host machine              1       High accurate thermostatic water tank          1        Testing software (in CD)                           1       Operating manual                                     1       Quality certificate                                       1              Calibration standard sample (300*300*26mm)     1(optional)       Calibration sample certificate                   1(optional)                   Packaging & Shipping   1 Delivery date: 30days  2.Payment terms: TT 30% in advance as the deposit, the balance to be paid before shipment.  3.Package: standard exporting plywood case.     Company Information
