sorry
the new probe is a milwaukee ma921b/2 the unit is a american marine the unit started climbing up in readings over a week or so so i tried to recal but i could only get it to sit a 4 and 5.53 not 7 when i tried the new probe it was the same but i'am wondering why the probe wasn't packed in gel and is this stainless tip a new thing
