range
-60 to +300 °C
-20 to +70 °C
Information: This probe connects to testo 635-2 only
An additional probe for measuring outer temperatures is
required when determining the U-value e.g. 0602 1793 or 0613
1001 or 0613 1002.
*when used with an NTC or wireless humidity probe for
measuring outside temperature and 20 K difference between
the air inside and outside
