Intuitive climate measurement
Suitable testo 440 probes are also available for critical process control measurements, for which maximum precision and resilient equipment are essential. Ideal for industrial environments where temperatures are high, as well as for laboratories, where it is essential to record even the smallest values with a high degree of accuracy.
Intuitive measurement menus
Clearly structured measurement menus are programmed into the measuring instrument and lead to accurate results.
Convenient measurement
Do you carry out measurements in environments where Bluetooth is not possible?
No problem: simply switch the probe head over from Bluetooth to the cable handle and you’re ready to go.
High-precision probes
Fume cupboard probes for laboratories/clean rooms; vane probes for laminar flow measurement;
Humidity probes with an accuracy of
Intelligent calibration concept
Only the probe heads need to be calibrated. You can carry on working with the measuring instrument, handle and another probe.
