Overview

Dual-band emissivity testing is a method used to measure the emissivity of a material across two distinct wavelength bands. Emissivity, a key thermal and optical property, indicates a material's efficiency in emitting thermal radiation. This testing is crucial in applications such as thermal imaging, aerospace, and materials science, where understanding a material's radiative behavior at specific wavelengths is essential for accurate thermal management and analysis.

Appointment Notes

Testing Method:
The instrument uses point-source testing (i.e., one data point per test), not full scanning. Each sample is typically tested 9 times, and only the average value is provided.

Powder Samples:
The powder volume must be at least 1 mL.

Bulk Samples:

Round Samples: Diameter of 2–4.4 cm.
Square Samples: Edge length of 2–3.1 cm (preferably close to 3.1 cm).
Thickness should ideally be greater than 1 mm; thinner samples may allow transmission, which affects accuracy. The surface should not be overly rough.
Thin Film Samples with Substrates: Film thickness should preferably exceed 10 microns; thinner films are generally inaccurate for testing.

Analytical Service Minimum order requirement: $250 per order. A $200 handling fee will be applied if order is below $250.

Please contact sales@msesupplies.com for additional information and instructions on our Analytical Services program. Confirmation of the sample(s) requirements, SDS sheets and additional information is needed prior to processing the Analytical Service order.
