[Terry M. Hunt]

Dug out the original 195 unit that was in the engine previously to test it and get a better idea of how to recognize when it was opening. It still works fine and the opening and closing events were obvious. Bought the 180 Napa stainless steel version and tested it with my infrared thermometer instead of the meat thermometer used previously and it worked just fine. Tried the infrared on the Robertshaw a couple more times, but I swear I can’t detect that any movement occurs even up to 220 . Makes me very reluctant to use it, so I guess I now have another piece of garage wall art to hang up.
