TESTO 645 Instruction Manual page 38

Standard indoor air quality probe up to +70 °C 0 to 100 %RH, probe
Highly accurate reference humidity/temp.
probe incl. calibration certificate
Robust humidity probe e.g. for measuring
material moisture equilibrium or for measure-
ments in exhaust ducts up to +120 °C
Robust high temperature probe up to +180 °C 0 to 100 %rH
Flexible humidity probe, does not retain shape
for measurements in inaccessible places
Pressure-tight probes for measuring remai-
ning, e.g. in compressed air systems
Flexible, humidity probe (retains shape) for
measurements in inaccessible places
