+1 on just leaving it be. I have Blichmann's with the thermo's mounted & they're great... as a general guideline, not an exact temp.
I'm a big fan of using the alcohol filled (they stopped selling the mercury ones a while back, not sure when) lab thermometer to calibrate my digital traceable workhorse thermometer. The mercury/alcohol ones are typically spot on & don't require recalibration, but the bi-metal & digital ones will drift. I just calibrate within a few degrees of my working temps (if I'm mashing I'll nuke a water sample to 150-160ish, when I'm cooling I'll recalibrate at 60-70ish, etc). That way I don't have to worry about a broken glass thermometer or its contents & I still know my digi is accurate. I use a recirculating mash, so I don't worry about hot/cold spots - I've double checked & am comfortable with the minor variances - but you can do the same thing with a long stem thermometer instead of the digi.
