I had an oven temp meter. Was in leather case, maybe robinair or something, years ago. Was really good, had a semi-rigid probe permanently mounted to meter. I would place it in center of oven and it would stay. But, somewhere along the line it grew legs and dissapeared from my old job where i had my tools, Never found another one like it. I use several meters now, my craftsman with temp probe. I have to finde another good one like the one I had.
