Dry Ice/ Acetone temp (pics)

[Wolf Creek Forge]

I just thought Id post these pics after reading several times on various sites about the temp of dry ice / acetone bath..I did a lot of research on it before trying and actually read on a couple websites (where someone had posted) that the dry ice/acetone bath will only get down to about -70* fahrenheit and not to the -95* rquired for RA reduction..Well here is a pic of the dryice/acetone bath and a pic of the thermocouple readout(I know its right)..I took this pic at -102.1 fahrenheit..It didnt stop there, it actually got down to about -106* fahrenheit..just though some might find it interesting..

 

[Error 404]

Dry ice / acetone will maintain -78 C I believe, not F. -78 C = -108.4 F.
