I had one in my old normally aspirated 182, and there is one in my turbo.
Don't know if either was standard given both planes were well used when I
bought them. In the non-turbo 182 the carb temp gauge was useful since the
plane had a tendency to get carb ice. I got it a few times. In the turbo it
is almost impossible to get the carb temperature low enough to allow carb
ice to form. I have never used the carb heat in the turbo except during
run-up.

I read my share of posts and this is the first time I've noticed someone
mentioning a carb temp gauge.

Is it a nice luxury, or not overly necessary?

Is it a standard piece of equipment on turbo's?

Are they ok in reliability (accuracy) and longevity?

Do people, without them, install them because carb temp gauges are on
their
*someday* list?
