OK, I actually don’t have anything to say about Simplicity, but the new dvd’s and Digital Thermometer (perfect for tempering) are in Products . Briefly, it measures in both Celsius or Fahrenheit. The temperature range on this thing is amazing: -58 f to +1382 f ! It comes ready to go with a K-type thermocouple and a 9v battery installed. I have checked half a dozen for calibration, and at 0 C and 100 C, it was no more than 1 degree off, if that. Perfect for tempering. They (and the dvd’s) are $30.00 each and in my opinion, would make great holiday gifts.
