THERMOMETERS
THE THERMOMETER SPECIFIED IN THE INSTRUCTION MANUAL FROM Robert Warren is:
[ 2'' dial thermometer with 1/2'' MIP thread, Range 50° to 220° ]
<SOURCE : '' Building an Ethanol Still & Making your
own fuel, by Robert Warren'' Page 5 : Bill of materials for the charles 803, Item 8 >
That leaves a great deal of choice as to the actual unit used
either analog or digital as well as a wide price range.
