You wouldn't want to stick the meter to the outside of the double wall pipe anyway. It wouldn't tell you anything. I also have double wall stove pipe and bought a condar probe thermometer for 23$ that works great for reading the actual internal temp of the flue. Class A chimney is rated for 1000 degrees continuous and way higher for short times.
The rutland magnetic meter in the photo is meant to be stuck to the outside of a single wall stove pipe. At least that's what the "normal/overfire/too cold" designations refer to. You can use it on the stove, which I do, but disregard the range designations.
Your steel stove is fine to 800 degrees or until parts begin to glow. 450 is child's play.
