Happy New Year 2010!
I recently purchased a Tel-tru thermometer on eBay at a very good price. Installed it in the WSM lid opposite the top vent. Tested it i boiling water and was within one degree.
Prior, I was using my Performer therm thru a cork in one of the holes in the top vent. The Weber therm was also checked in boiling water and was within 5 degrees of 212 degrees.
Now the $1 million dollar question: the difference between the two therms was 40 degrees.
I do not understand why such a big difference?
