testo 400 in laboratories and clean rooms.
Measurements in Laboratories and Cleanrooms
Suitable testo 440 probes are also available for critical process control measurements, for which maximum precision, and resiliency are essential. Ideal for industrial environments where temperatures are high, as well as 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: switch the probe head from Bluetooth to the wired handle and you’re ready to go.High-precision probes
Fume hood probes for laboratories/clean rooms; vane probes for laminar flow measurement;
Humidity probes with an accuracy ofIntelligent calibration concept
Only the probe heads need to be calibrated. You can continue working with your meter, handles and other probes.

When a high degree of precision is required
The specially designed, high-precision probes for the testo 440 Multifunction IAQ Meter can assist you with these applications, for example:
Reliable measurement of laminar flows (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 %
When a high degree of precision is required
The specially designed, high-precision probes for the testo 440 Multifunction IAQ Meter can assist you with the following applications:

Use these probes with the testo 440 to measure with precision:
testo 440 dP with differential pressure sensor
For pitot tube measurements and checking filters on air conditioning systems, we recommend the testo 440 dP, which includes a differential pressure sensor.
