ET-100 Handheld Thermal Emissometer
- In-Band Reflectance & Emittance
- Easy to Use
- ASTM Compliant
- Dual Angles of Incidence
- Save Time
- Room Temperature Samples
Total Hemispherical Emittance Measurements
The ET-100 measures directional reflectance from 1.5 to 21 μm and, based on those values, calculates directional and total hemispherical emissivity. The ET-100 emissometer conforms to ASTM E408, the standard test method for the determination of emittance using a portable instrument. In-band reflectance data for six discrete bands.
