Flexible humidity probe
0628.0022
Description
Humidity probe with 1.5 m long, flexible cable.
A humidity sensor and a temperature sensor are
situated in the tip of the probe (sintered cap).
Application
Humidity and temperature measurements in uneasily
accessible places e.g. in drilled holes, pipes, as well as
climatic test cabinets, medical analysing instruments,
incubating cabinets, etc.
The flexible humidity probe has been developed for
applications with the
testo 445, 645
