I was assuming that'd you want to be able to pull the probe for use in other applications?
Not necessary. I got this probe just for this application.
But, I was thinking about another way to skin this cat.
Look at these pictures. I threaded the thermocouple wire from the thermometer I was using with the (now gone) IR2 through the probe hole, and used BW's foil tape to tape it to the bottom of the UFO. The probe should be right in even the smallest bean mass.
What have I missed in this possible solution
?
