IAQ Measuring Instrument-testo 440
Use the testo 440 air velocity and IAQ measuring instrument in combination with high-quality probes to measure and store all air velocity and IAQ parameters (please order probes separately). Up to 3 probes can be connected simultaneously: a Bluetooth probe, a wired probe and a temperature probe with type K thermocouple connector. Automatic probe detection and clearly structured measurement menus guarantee simple operation and will make your day-to-day work easier.
With the testo 440 multipurpose measuring tool, you can measure in only a few clicks.
Carry out your measurements fast and simply since the air velocity and IAQ measuring device recognises each attached probe automatically. This implies that while changing probes, you won’t have to manually reset the settings. Evaluating the volume flow in ducts/at outlets, funnel measurement, measuring the degree of turbulence, estimating the cooling/heating output, mould detection, and long-term measurement are all supported by well designed measurement menus.
More applications, less equipment: wireless and space-saving
A universal handle can be linked to any probe head, allowing you to master more applications with less equipment and conserve space.
The Bluetooth handle makes it easier to conduct your measurement and ensures that the casing is less cluttered with cables. It makes it possible to carry out measurements without any bothersome cable connection and it transfers readings up to a distance of 20 m. Use the cable handle to connect testo probe heads as a practical option. If Bluetooth signals are not allowed, this is a benefit.
Data management for practical measurements
Up to 7500 measurement protocols may be stored in the multifunction measuring instrument, which can be read through a USB port and processed as a CSV file on your computer (e.g. with Excel). You may print a report printout of the measurement data immediately on site with the testo BLUETOOTH/IRDA printer (please purchase separately).
Intelligent calibration concept for optimal precision
When you use our digital probes, you can count on precise measurement findings since the measuring device eliminates measurement ambiguity. Only the probes must be sent in for calibration. As a result, the multifunction measuring device can be used indefinitely.
