Introduction
DRPL-II coefficient of thermal conductivity tester (plate heat flow plan method)
A, this
The instrument adopts the international fashion heat flow plan and thermal resistance coefficient of thermal conductivity detection method, match the computer to realize automatic detection and generate the experiment report. From the applicable materials, refractories, low thermal conductivity materials heat conduction performance test, widely used in universities and colleges, scientific research institutes, quality inspection, mines.
The instrument is the reference standard GB/T10295-2008 (adiabatic material thermal resistance and steady-state related properties of determination of heat flow plan method) and ASTM C518-the heat flow plan with determination of steady heat flux and heat transfer characteristics of the test method.
B, system composition:
A) hot surface heaters, high precision temperature control, fluctuation program-controlled table is less than 0.2 degrees, hot surface temperature measurement resolution 0.01 ℃.
B) the constant temperature control temperature grim sink, less than 0.05 degrees, the grim fluctuations in temperature measurement resolution 0.01 ℃.
C) heat flow sensor adopts imported sensor, 0.01 W/resolution M2Uv, display table with high precision digital display table, arguing 0.1 mv UV.
D) the vacuum system to guarantee the test environment from the external influence.
E) calculation formula: λ = (W × H) / (train T × S)
λ-thermal conductivity;
W-heat flow;
T-Train the temperature difference between two sides;
S- - - -the sample area.
C, main parameters:
1, the thermal conductivity test range: 0.002 2 W/MK;
2, hot surface temperature range: 99.99 ℃; the room temperature-
3, grim temperature range: 0-99.99 ℃;
4, sample size: 200 x 200 x (5-20) mm;
5, precision: less than 5%.
