Default pro exotics temp gun and emissivity

While navigating in rcmushroom I saw this http://rc-mushroom.com/product_info....oducts_id=1458 Is it a good or bad temp gun? (it has interchangeable emissivity)
About emissivity, in Duratrax temp gun instructions I read that the emissivity of anodized aluminum is 0.77, but I think that the emissivity depends, also, about the color of the anodized aluminum (emissivity changes between black or purple aluminum for example). Do you know any webpage (or something) where I can view a table about this? Thanks

Emissivity does matter as to the texture of the surface and how porous it is. The are not looking for emissivity settings for anodized aluminum anyways because that is not what you are reading. You are reading the head button (shiny aluminum) or the glow plug. I have a high end Raytek that has adjustable emissivity and when I got it, there was a chart. Lemme see if I can find it... BINGO, here you go...
