    testo 400 universal Air Flow and IAQ instrument – features:

    Impressive IAQ measurement technology
     
    • High-precision, location-independent and integrated differential pressure sensor meeting the NEBB Instrument requirements for Air pressure
    • Integrated absolute pressure sensor
    • Measures all IAQ-related parameters: Flow, temperature, humidity, pressure, illuminance, radiant heat, turbulence, CO2 and CO
    • Numerous connection options for probes: 2 x cable probes (TUC), 4 x Bluetooth® probes, 2 x type K thermocouple probes
    • Compatible with a wide range of available Bluetooth® and cable probes – so you’ll be equipped for any measuring task
    • For high-precision measurements and less downtime: Adjustment function at up to six measuring points for zero-error display, probe heads can be replaced without restarting the IAQ measuring instrument, high-quality probes with an intelligent calibration concept (probe calibration independent of the measuring instrument)
    • Long-term monitoring of the indoor air quality: Order the IAQ data logger for carrying out long-term measurements with the testo 400 IAQ measuring instrument. While the stand-alone data logger is carrying out the IAQ measurement, you can use the IAQ measuring instrument for measurements elsewhere
