Anybody any useful recent experience?

Do you mean one which reads the true temperature as measured by a
sensor,
rather than just a digital display of what it's meant to be?


Yes


I think any sensible manufacturer would not offer this as it would
clearly show the variations in temperature as the control system cut in
and out causing some customers to be dissatisfied and letters of complaint.
I can't imagine other than a very high end oven employing a 3 term PID
controller when a gradual variation +/- a few degrees from a simple bang
bang controller would make no discernible difference in cooking
performance.

I've simply got a couple of "floating" thermocouples in my double oven
wired up to a standard display. It is interesting how rapidly the air
temperature drops when the door is opened, and how relatively slow it is
to recover. I regularly use an IR thermometer to check the temperature
of the linings, and sometimes use a probe in the joint. Several decades
ago Cannon had an oven which came with a built-in probe and display.
