Abstract
An emittance meter which utilizes internal standards by Au plated mirror and low temperature blackbody furnace as low and high emittance standards respectively has been developed. The obtained emittance value of which systematic error was compensated had accuracy within ±0.01 and precision within ±0.003. The long term drift of measured emittance value was also checked and confirmed to be within ±0.01 for one year continuous operation.
