The American D&S AE1/RD1 emissivity measuring instrument is suitable for detecting emissivity of thermal insulation coatings using the radiometer method, meeting the requirement of 6.5 hemispherical emissivity in the standard JG/T 235-2014 "Reflective Thermal Insulation Coatings for Buildings".

Detailed parameters:1. Principle: Radiometer method for detecting emissivity; 2. Measurement range: 0.03~0.95; 3. Test accuracy: maximum allowable error range -0.015~+0.015; 4. Reproducibility: Range not exceeding -0.01~+0.01; 5. Output: 2.4 millivolts (sample with a radiation rate of 0.93 at room temperature): 6. Linear relationship: The linear relationship between the detector output value and the radiation value does not exceed -0.01~+0.01 units; 7. Using a blackbody slot can ensure that the temperature of the calibration standard version and the sample being tested are consistent; 8. Sample temperature: should cover room temperature~82 ℃; 9. Sample diameter: can measure smooth samples with a diameter>3.8cm (customizable detector for measuring uneven materials)
