Highly accurate humidity / temperature probe 0636.9741
Application information en
Only specific humidity sensors with a special basic capacity are used for the
highly accurate humidity / temperature probe.
The probe undergoes comprehensive calibration and testing procedures. It
is tested before delivery in the Testo laboratory and a calibration certificate is
issued.
Note
The calibration buttons are sealed with a calibration sticker.
The precision probe can be tested using the monitoring and adjustment set.
The salt containers are not suitable for calibrating the probes.
We recommend an annual calibration by Testo.
Heavy electromagnetic load (interfering irradiation from external sources) can
lead to incorrect measurements. With the enclosed folding ferrite the probe
complies with the guidelines in accor dance with 2004/108/EEC.
Attach the folding-ferrite to the connection cable:
300mm
Instrument
plug
The cable can also be used for other Testo probes.
