Multifunction instrument Testo 400
 


Testo New Professional Class - The reference measuring instruments. Testo 400 is the multi-function instrument designed to simplify the measuring tasks of professionals and tradesmen.

Measures and records
  • Temperature with accuracies to <0.1 °C/°F. Probes have calibration for adjustment capabilities.
  • Humidity/Dew point, complete Mollier diagram values.
  • CO and CO2 with ambient levels
  • pressure, differential pressure and also absolute pressure
  • Velocity measurements using thermal, vane and pitot tube probes.
  • It also calculates volumne flow, max, min and values mention of ASHRAE Speck's
  • The mV/mA measurement input easily checks transducers outputs.
  • Logs data with date, time and location over long time periods using the logger function in the measuring instrument.

The following functions are upgradable
  • The measuring instrument guides you through volume flow calculations and calculates, for example, immerson depths, number of measuring points etc.
  • Calculates measuring inaccuracies on location
The precision multifunction instrument and datalogger measures temperature, CO, CO2, rpm, mV and mA, % RH, pressure and velocity.

Features
  • Rapid measurement with accurate temperature probes. The instrument can extrapolate the final value for faster response times.
  • Highest precision due to system calibration (measuring instrument + probe) Calibration data is saved in the probe.
  • Calculates all of the physical humidity parameters in the Mollier diagram
    • relative humidity (% RH)
    • dew point, pressure dew point (tp, tdp)
    • absolute humidity (g/m3)
    • humidity levels (g/kg pressure-compensated)
    • humidity, wet temperature °C and °F
    • water vapour partial pressure in mbar/hPa
    • Enthalpy kcal/kg
  • Humidity probes for every application, from remaining humidity to high humidity levels
  • Indent guaranteed long-term stability
  • Highest accuarcy ± 1 %
  • All of the conventional types of averaging are available
  • Volume flow measurement (cfm, m3/min, l/s)
  • Duct dimensions in the various measurement locations can be saved in the instrument. When the measurement location is called up the saved dimensions can be used to measure cfm.
  • Measures the barometric pressure (absolute pressure) as a reference value or for the correct Pitot tube measurement.
  • Measures turbulence levels.
  • Measuring instrument and display are integrated in the probe
  • Very practical one-hand operation
  • No awkward cable connections
  • Robust, waterproof design, can be wiped clean
