Good morning .

Maybe some one has been use the ET10 Reflectometer Measures Emissivity.

Or maybe exist another like this in the market?

I would not expect an emissivity measurement done with this device to match the emissivity measurement done with your camera. It will be better than using tables though. When you do an emissivity measurement with your camera you actually calculate a grey emissivity equivilent, based on the sprectral properties of the material (at its current temperature) and the specific response of the detector used. The emissivity of an equal surface can vary from camera to camera (even in the same waveband) as the response curves for the detectors will be different. This device will not know the exact response of the detector in your camera, so it might not be such a good idea if you need a high level of accuracy.
