TEMP 2000A, Portable Emissometer/Reflectometer

AZ Technology's TEMP 2000A handheld emissometer/reflectometer is the recognized replacement for an aging Gier-Dunkle DB100 as suggested on page 23 of the following 2005 NASA Technical Paper,

"The simplest method of determining emittance is with a portable infrared reflectometer such as the [Gier Dunkle] DB100 or the AzTek [AZ Technology] Temp 2000."

-- Kauder, L. (2005) NASA/TP-2005-212792, pg. 23.

The AZ Technology TEMP 2000A Portable Emissometer/Reflectometer is compact, lightweight, rugged, and ergonomically engineered for ease of use in the field or in the laboratory to determine ambient temperature total emittance.

The TEMP 2000A can be conveniently used in a laboratory setting (top right image) where samples can be sat atop the instrument and left while repeated measurements are being taken. The TEMP 2000A can be used as a portable unit (bottom right image) via use of a battery pack and vest.

The TEMP 2000A, by virtue of an advanced optical system, provides a portable emissometer/reflectometer that performs total hemispheric reflectance measurements from less than 3 to greater than 35 micrometers wavelength and is not limited in wavelength range due to filters, windows, or coatings, placed in the optical path. The TEMP 2000A optical system has been designed to minimize losses, to facilitate and maintain optical alignment, and to utilize the features of AZ Technology's patented ellipsoid collector (US Patent Number 5,659,397) that allows compactness for portability, efficiency, and measurement accuracy. The TEMP 2000A provides improved performance and maintainability over the no longer produced Gier Dunkle DB-100 IR Reflectometer** and in accordance with the ASTM E408 standard.

The table below lists specifications for the TEMP 2000A.
