Product review (5 stars): Accurate and Easy to Read
A perfect size for a multi-function thermometer/hygrometer.  It can be read across a room but still fits in a small area.  It has a unique calibration feature that allows the user to correct the digital thermometer.  By comparing the digital readout with a normally more accurate liquid column thermometer, the user can calibrate the digital readout.  However, I found that the digital reading was within my ability to accurately read the liquid thermometer (both read the same within full degrees).  Time and date functions are included as well as daily highs and lows for temperature and humidity. Priced right!
