The thermometer reads 0.5-0.7 degrees Celsius Constantly higher temperature did the three other thermometers I tested it against (including at Mustek accurate multimeter). The hygrometer is not very accurate either. So the outside sample always gives a different reading (more than one degree) did the inside Even When They are Placed side by side. So the unit can not even agree with itself! Finally the outside probe can not read humidity but only temperature, Something That is not CLEARLY Stated in the description.
