Portable Reflectance Tester D&S AERD

Can quickly measure the emissivity of various solid surfaces.
Hemispherical emissivity: The ratio of the radiation emissivity of a thermal radiator in the hemisphere direction to the radiation emissivity of a full radiating body (blackbody) at the same temperature.
ASTM C1371 - 15 Standard Test Method for Determination of Emittance of Materials Near Room Temperature Using Portable Emissometers.( Measurement of hemispherical emissivity of materials at room temperature using a portable reflectance analyzer.
HG/T 4341-2012 Thermal Reflective Insulation Coatings for Metal Surfaces (Hemispherical Emissivity).

The main features of the portable reflectance analyzer D&S AERD are:

1. Digital display emissivity device.
2. Short measurement time (about 15 seconds).
3. Low price and easy operation.
