Long-Term Drift-Free Thermohygrometer
The compact instrument with
built-in humidity probe head for
measuring air moisture and
temperature. The large 2 line
display shows humidity, wet bulb
temperature or dewpoint as well
as temperature.
When measuring at hard-toaccess points, the humidity probe
head can be easily removed and
attached to the handle via the
probe cable (accessory).
Alternatively, the readings can be
transmitted wirelessly over wide
distances from the probe to the
measuring instrument. To do this,
the humidity probe head is
attached to the radio handle
(accessory) and the radio module
(accessory) is added to testo 625.
