3System description
You have acquired a probe. This probe comprises a cable handle, a probe
head and, if applicable, additional probe-specific accessories.
The cable handle can be connected to all the system’s probe heads and
attachments. The graphic below shows what options the system offers.
You will find detailed information about how each of the probes works
along with the testo 440 measuring instrument in the corresponding
chapter of the instruction manual for the measuring instrument.

4.1 Cable handle for connecting testo 440
probe heads (0554 2222)
Application
The handle is used to connect probe heads to the testo 440 measuring
instrument.
Pay attention to the information on the measuring process in the
detailed instruction manual for the measuring instrument. You will find
this at: www.testo.com.

4.2 Hot wire probe, including temperature
and humidity sensor (0635 1572)
Use
In conjunction with the testo 440, the hot wire probe is suitable for flow and
humidity measurements in ventilation ducts.

7 Cable handle 8 Cable
CAUTION
Damage to sensor possible!
- Do not touch sensor!
- Put the protective sleeve on after the measurement.
Low flow velocities may result in greater measurement uncertainties
during temperature and humidity measurement. The probe should be
switched on outside a duct under the following conditions:
Ambient temperature: 20°C
Flow: approx. 0 m/s.
Connect hot wire probe to the handle
1 Turn quick-release connector,
viewed from the handle end, through
90° anticlockwise until it locks in
place.
2 Insert handle adapter into the handle
(pay attention to coding).
3 Turn quick-release connector back
through 90° until it locks in place.
