* This specifies the overall error in the logged readings, for relative humidity measurements between 20 and 80%RH
** This specifies the overall error in the calculated dew point, for realtive humidity measurements between 40 and 100%RH at 25°C
*** Depending on sample rate, ambient temperatures and use of alarm LEDs † At temperatures below -20ºC (-4ºF) the LCD will exhibit slower response times of approximately 10 seconds
