Multifunction Meter – Testo 440

Producer:
SKU: TESTO-0560-4401 Category:
  • Intuitive: clearly structured measurement menus allow measurement of volume flow, turbulence level, cooling/heating output, mold detection
  • Wireless: Bluetooth® probe for more convenient measurement and less cable clutter (probe order option)
  • Clear overview: large graphic display shows 3 measurement parameters simultaneously
  • Safe and reliable: data storage with internal memory and USB port for data export

Use the testo 440 multifunction measuring instrument to measure air velocity and IAQ parameters thanks to a combination of high-quality probes (optional). Up to three probes can be connected simultaneously: a Bluetooth probe, a wired probe and a TC type K thermocouple temperature probe. Automatic probe detection and clearly structured measurement menus ensure the simplest operation and will make your daily work easier than ever.

testo 440 multifunction meter: more applications, less equipment

Versatile: The testo 440 multifunction meter can be connected to a wide range of probes – so you can cover more applications with less equipment

The Bluetooth handle makes measuring more compact and convenient, with Bluetooth connectivity up to 20 metres. Or you can choose a practical alternative with a cable probe handle to connect Testo probes in cases where Bluetooth is not available.

Real-time measurement data management

The multifunction measuring instrument stores max. 7500 measuring values, which can be read out via USB and further processed as CSV files on your PC (e.g. with Excel). With the testo BLUETOOTH/IRDA thermal printer (optional), you can optionally print out measurement data reports directly on site.

Advantages of measuring with the testo 440 multifunction meter

Accurate, reliable in ducts and at air outlets

  • Various probe types can be connected: thermocouple and vane probe (Ø 16 mm) for measurements in ducts; large vane probe Ø 100 mm for measurements at air vents / ceilings
  • Calculate volumetric flow quickly: in the measurement menu, simply configure the geometric dimensions of the pipe cross-section and you can see the volumetric flow displayed on the measuring device immediately.
  • You will even find it easy to carry out measurements in particularly large ducts. Thanks to the extendable telescopic probe with a length of up to 2 metres.
  • Carry out measurements at air vents/ceilings easily and without the use of a ladder. Mount the vane probe (Ø 100 mm) with a telescopic tube and a 90° connection angle.
  • Use the vane probe in combination with the testovent measuring funnel and flow rectifier to check the inlet/outlet air flow at air intake grilles, ventilation grilles and vortex discharge outlets.
  • Integrated magnet on the back of the testo 400 for secure attachment of the multifunction measuring instrument to metal surfaces (e.g. ventilation ducts)

Long-term indoor air quality (IAQ) monitoring

  • Probes to suit your requirements: CO2, CO, temperature and humidity probes
  • Easy to use: enter measurement intervals in the menu to perform long-term measurements and intraday monitoring
  • Internal memory up to 7500 measurement values

Turbulence measurement in accordance with EN ISO 7730 / ASHRAE 55

  • High accuracy, even at low air velocities with turbulence probe
  • Automatic calculation of risk probabilities and disturbance levels according to EN ISO 7730 / ASHRAE 55
  • For convenient measurements at different heights, we recommend using our measuring feet for comfort measurements.

Probes for clean rooms and laboratories

  • Fume hood probe for high precision air velocity measurement in fume hoods
  • Thanks to its low start-up speed of 0.1 m/s, the high-precision vane probe (Ø 100 mm) is ideal for airflow measurements in cleanrooms.
  • High precision temperature/humidity probe (0636 9771 or 0636 9772) with accuracy ±(0.6 %RH + 0.7 % measured value) in the measuring range 0 to 90 %RH for humidity measurement in clean rooms
