The Testo 400 allows rapid measurement with accurate temperature probes. The instrument can extrapolate the final value for faster response times. It has the highest precision due to system calibration (measuring instrument + probe). The measuring instrument and the display are integrated within the probe, which is where the calibrated data is saved. The Testo 400 is a very practical one-hand operation with no awkward cable connections. It is a robust measuring instrument, with a waterproof design and can be wiped clean. The Testo 400 calculates all of the physical humidity parameters in the Mollier diagram and has humidity probes for every application, from remaining humidity to high humidity levels. It can also be used to measure barometric pressure and turbulence levels.

Key Features

  • Checks indoor air quality or the air exchange number using CO2 probe (See DIN VDI 1946)
  • Checks transducers using the MV/mA measurement input
  • Checks ventilation in underground garages using CO probe
  • Logs data with date, time and location over long periods using the logger function in the measurement instrument
