ET-10 Emissometer

Emittance at 3-5 and 8-12 microns

The ET-10 Emissometer answers the long-standing need for measuring emissivity as an entry parameter for calibrating infrared thermography devices. The ET-10 measures total reflectance and directional emissivity at 20 degrees angle of incidence for 3-5 and 8-12 microns. The 8-12 band can optionally be extended to 14 microns.
