Testo also offers suitable probes that are compatible with the testo 400 and testo 440 for control measurements in critical processes where maximum precision and resilient equipment are crucial. They are not only ideal for laboratories and cleanrooms, where the smallest values are measured with the utmost accuracy, but also for industrial environments subject to high temperatures. The testo 400 is your first choice when maximum conformity with standards is required and complete documentation.
Intuitive measurement menus Clearly structured measurement menus are stored in the measuring instrument to guide you reliably and efficiently through the respective application.
Convenient measurements 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.
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.
