In order to determine the flow speed and the volume flow in the ventilation duct, the testo 440 set is an effective measuring device for starting directly with your work!
The testo 440 set contains a compact hand-held measurement device, a Bluetooth-hand grip and hand-grip adapter, a fan-wheel probe (Ø 100 mm) and impeller probe (Ø 16 mm). Both probes are Bluetooth enabled and have a temperature sensor. The testo 440 hand-held meter is delivered with inserted batteries and is immediately ready to use! A suitable combination case is supplied for the set!
The handheld meter has a large, illuminated color display and possesses a structured measurement menu, in which time and point-based determination of average value, average volume current, current measured value as well as min./max. values are indicated. The dimension and geometry of the channel cross-section can also be entered to calculate an exact calculation of the volume flow. Further measurement menus such as long-term measurement and volume measurement with funnel are also possible.
The handheld testo 440 meter stores and evaluates your measurement data and can secure up to 7,500 measurement protocols in its integrated measurement data storage.
Measurement protocols can be read via a USB interface and processed as CSV file on the computer (e.g. with Excel).
Practical magnets for the attachment of the measuring device to metal surfaces (e.g. flow channel) are integrated in the handheld measuring device. An automatic detection of the probes is available.
The included impeller probes can be easily connected to further probe heads or telescopes. The button on the handle saves the individual measured values. The Bluetooth hand-grip takes care of your measurement more comfort and less tangle of cables in the case!
Reliable readings thanks to ISO calibration
Diagnostics tools used in an environment that complies with ISO 9001 standards require ISO calibration. Moreover, most safety inspectors as well as accredited testing and certification bodies need to use ISO-certified equipment.
