i woul pin the sensor to the side of the bator jusy above the lipImho a major design flaw:Its a clear piece of plastic stapled to the sensor. Miller mfg says "do not remove clear plastic from sensor". It moves all around with the auto turner. I have a brinsea spot check and a accurite that reads the same as the brinsea. When the sensor moves the temp spikes.
And when a chick hatches and moves the sensor...It goes haywire
