    Climate measurement improved to the max.

    testo 400 in laboratories and clean rooms.

    We recommend: testo 400 Multifunction IAQ Meter

    For high-precision measurements of all climate-related parameters in clean rooms and laboratories

    • Intuitive measurement menus: Clearly structured measurement menus are pre-programmed in the meter and guide you through the respective application.

    • Convenient measurement: Do you measure 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 hood probes for laboratories/cleanrooms; vane probes for laminar flow measurement; humidity probes with an accuracy of

    • Intelligent calibration concept: Only the probe heads need to be calibrated. You can continue using the instrument, handle, and another probe.

    Precise measurement technology for laboratories and cleanrooms

    High degree of precision is required

    The specially developed, high-precision probes support you in these applications, among others:

    • Highly accurate and position-independent differential pressure measurement (only with the testo 400)

    • Reliable measurement of laminar flows

      Accurately recording even the smallest differences in 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 %
