TESTO 440 - SET OF MULTIFUNCTION METER + THERMAL PROBE 0563 4400
The TESTO 440 set with a thermal anemometer probe is a highly versatile and professional measuring instrument designed for ventilation and air-conditioning engineers as well as indoor air quality specialists. The device stands out for its intuitive menu, extensive functionality, and compatibility with a wide range of probes, making it exceptionally flexible for service and inspection applications. The set includes a measuring head, a telescopic thermal probe (hot-wire type), and a transport case, ensuring it’s ready for immediate use and easy to carry.
In terms of applications, the TESTO 440 set allows for air velocity measurement in ducts, calculation of volumetric flow, temperature measurement, absolute pressure readings, and indoor air quality analysis — all depending on the connected probe. The device features a large, easy-to-read display, internal data storage, and USB export capability, making it suitable not only for quick field measurements but also for professional reporting. With its compact and ergonomic design, the TESTO 440 performs excellently in the field — in service, maintenance, and industrial environments.
As for the technical specifications, here are the key parameters: the instrument measures 154 × 65 × 32 mm and weighs approximately 250 g. Operating temperature ranges from -20 °C to +50 °C. Power is supplied by three AA (1.5 V) batteries, providing up to 12 hours of typical operation. The thermal probe measures temperature from -20 °C to +70 °C, with accuracy of ±0.5 °C and resolution of 0.1 °C. The absolute pressure range is +700 … +1100 hPa with an accuracy of ±3.0 hPa. For air velocity (hot wire), the range is 0…30 m/s, with a resolution of 0.01 m/s and accuracy of ±(0.03 m/s + 4 % of the measured value) between 0…20 m/s, and ±(0.5 m/s + 5 % of the measured value) between 20.01…30 m/s.
The TESTO 440 thermal anemometer set is an investment that pays off through reduced measurement time, improved work efficiency, and enhanced data precision. Thanks to interchangeable probes and configurable measurement channels, users can quickly adapt to HVAC, maintenance, or building inspection needs — both in standard and hard-to-reach locations such as ventilation ducts or technical ceilings. With its durable construction, portability, and expandability through additional probes, the TESTO 440 set proves to be a long-term, universal measuring solution for professionals.
