Multi-function Anemometer Testo 400

More intelligent. Faster. More efficient: the new generation of measuring devices for the indoor climate

This multifunction measuring device makes it easy to carry out indoor climate controls. They have universal probes, wireless and interchangeable without restarting the device.

The Testo 400 is equipped with a measurement assistant to perform all the necessary checks by limiting errors.

All data is visible at a glance thanks to the 5 “HD screen, they can be managed and reports can be edited without the help of a computer.

Versatile, it can be used in laboratories, clean rooms and industrial environments.

It offers maximum precision especially when measuring pressure and temperature.

Product highlights:

  • Display all measurements as a table or graph.
  • Zero adjustment faults in the device for even more accurate measurements.
  • A measurement assistant that helps you set up, perform and evaluate the measurement result.
  • The Testo 400 meets the accuracy requirements according to ISO 14644
