Review on 🌡️ Winters TCT Series Dual Scale Mild Steel Clamp-On Thermometer, 2-1/2 Inch Dial, 30 to 240 Degrees F/C Range by Mike Walters

The temperature is accurate, the scale is fairly easy to read, but I wish the scale had more numbers on the face. I know it's very picky. The only thing that bothered me was the spring that keeps it at the intended temperature of the whistle you are controlling. As I pulled the spring around the tube, it slipped out of the needle nose pliers and disappeared. I know I can buy a spring at a hardware store, but I just used nylon ties to hold it in place. The pipe temp never goes above 130F so that should be fine. If you don't have zip ties handy, get them, they come in very handy.
