Advantages of measuring with the testo 440 air velocity and IAQ measuring instrument

• Large range of connectable probes: hot wire and vane probe (Ø 16 mm) for measurements in ducts; large vane probes of Ø 100 mm for measurements at air/ceiling outlets
• Calculate volume flow quickly: in the measurement menu, simply configure the dimensions and geometry of the duct cross-section and see the volume flow displayed on the measuring instrument straight away
• You will even find it easy to carry out measurements in particularly large ducts. This is because the extendable telescope on the hot wire and vane probe (Ø 16 mm) with universal handle can be further extended using the telescope extension – enabling you to attain a total length of 2 metres
• Carry out measurements at air/ceiling outlets effortlessly and without using a ladder. Fit the vane probe (Ø 100 mm) with the extendable telescope with 90° angle and, if necessary, with the telescope extension (both can be ordered separately)
• Use the vane probes in conjunction with the testovent measurement funnels and flow straighteners to test incoming / outgoing air at plate outlets, ventilation grilles and swirl outlets
• Practical Bluetooth interface: use the air velocity probes to measure without having to deal with any bothersome cables, operate the measuring instrument by pressing the button on the handle of the probe, e.g. start or stop a timed mean calculation
• Use the practical magnets to securely attach the multifunction measuring instrument to metal surfaces (e.g. ventilation ducts)

• The right probe for your requirements: probes for CO₂, CO, air temperature and humidity are available as variants with Bluetooth or with fixed cable
• Easy to use: enter the measurement period and interval in the menu for long-term measurement and track it over the course of the day
• Internal memory for up to 7500 measurement protocols

• Attain a high level of accuracy, even at low air velocities, with a turbulence probe
• Automatic calculation of draught risk and degree of turbulence in accordance with EN ISO 7730/ASHRAE 55
• For convenient measurements at varying heights, we recommend using our measuring tripod for comfort level measurement. This makes it very easy to position turbulence probes in compliance with the standards

• Fume cupboard probe for high-precision air velocity measurement on fume cupboards
• Thanks to the low start-up speed of 0.1 m/s, the high-precision vane probe (Ø 100 mm) is ideal for laminar flow measurements in cleanrooms. Available as a variant with Bluetooth or with fixed cable
• High-precision temperature/humidity probe (0636 9771 or 0636 9772) with an accuracy of ±(0.6% RH + 0.7 % of m.v.) in the range 0 to 90% RH for measuring the humidity in cleanrooms
