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.
Measurements in laboratories and cleanrooms
- Intuitive measurement menus
Clearly structured measurement menus are programmed into the measuring instrument and lead to accurate results. - Convenient measurements
Do you carry out measurements in environments where Bluetooth is not possible?
No problem: simply insert the probe head from the Bluetooth handle onto the cable handle and you’re done. - High-precision probes
Fume cupboard probes for laboratories/cleanrooms; vane probes for laminar flow measurement;
humidity probes with an accuracy of < 1 %. - Intelligent calibration concept
Only the probe heads need to be calibrated. You can carry on working with the measuring instrument, handle and another probe.
The specially designed, high-precision probes for the testo 440 air velocity & IAQ measuring instrument can assist you with these applications, for example:
- Reliable measurement of laminar flow
- Accurately recording even the smallest differences in air velocity, from 0.02 m/s
- Measuring humidity in critical processes with an accuracy of 1 %
