Going to package sender for airbox temperature and 5 others.

I have an Ilec SC-7 Variometer that has a temperature read out. It is driven by tiny 3/16" cylinder x 3/16" long precision semiconductor thermal sender.
Here we are warming along with a thermocouple driven probe. Tracking is very very close to thermocouple driven probe. 32°F was spot on with snow cup. Sprayed some freeze spray and it went to at least -40°F. Here it is at 165°F.
