Probes

Probe type

Fast-action surface probe with

sprung thermocouple strip, also for

uneven surfaces, measurement

range short-term to +500°C, TC

Type K, Fixed cable

Temperature probe to determine U-

value, triple sensor system for

measuring wall temperature,

modelling clay included

Dimensions

Probe shaft/probe shaft tip

Measuring

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
