Product review (2 stars): Odd false temperature spike every night
Purchased this thermometer to track temperatures for ambient drug storage at a medical research facility.  This thermometer falsely shows a temperature spike overnight that baffled us until we placed another thermometer next to it overnight.  The other thermometer showed a maximum of 75.5F that night (very believable), while this one showed a maximum of 82 F.  All through the day, it agrees with other thermometers, but has a strange 7 degree spike every night.
