My oven seems to cook the outside faster than the inside
so I have used a laser temperature probe pointed at the chicken and adjusted the dial so that this value is 180C

That's not how you are meant to do it. 180 C is the oven temperature, not the temperature of the chicken skin. If you turned it up until the chicken surface became 180, that's way too hot, and of course it causes the exact symptoms you describe.
You should just set your oven dial to 180 C and use it that way. If it continues to burn on the outside, go down in the temperature until you find one at which, when you wait until the inside is done, the skin is not burnt. Then write down the time and (dial setting) temperature it needs, and continue using that, no matter what the package says.
