You wish to measure temperatures in laboratories with high precision? Then we recommend the multifunction measuring instruments testo 400 and testo 440. Both measuring instruments can be combined with multiple different probes – for monitoring all important air conditioning parameters in laboratories and cleanrooms. Whether universal or compact: At Testo, you will find the right multifunction measuring instrument for your requirement profile:
Intuitive measurement menus
Clearly structured measurement menus are stored in the measuring instrument to guide you reliably and efficiently through the respective application.
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.
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.
