A 180 stat will start to open at about 183 and be fully open close a tad above 200.

I find it best to use a thermal gun and once the water starts to make small bubbles turn off the heat and remove the pot from the stove, then with the gun watch until the temp gets down to 205 and only then drop the stat in.

It’s best also to do this test in a large volume of water so the temp drops slowly before you drop the stat in.
