testo 440 Set2 delta P Anemometer Datalogger function

The flow velocity and flow in ventilation duct to determine, the testo 440 Set an effective measuring device directly to the work to begin!

The set includes a climate meter testo 440 dP including differential pressure sensor, two impeller probe heads (diameter 100 mm and 16 mm), as well as a humidity/temperature probe head - all three can be plugged on the supplied universal Bluetooth handle.
Both Vane probe heads can be combined with the included in the set telescopic. The equipment is in a suitable combination case!
The meter has a large, illuminated color display and has a structured measurement menu by pressing and specific temporal averaging, average volume flow, current measured value, as well as min/max values are displayed. You can also dimension and geometry of the channel cross-section must be entered to calculate an exact calculation of the volume flow. Other measurement menus as long-term measurement and volume flow measurement with funnel are also possible.
The testo 440 meter collects and evaluates your measurement data and may be used up to 7,500 measurement protocols in its integrated measurement data memory.
Measurement protocols can be read via a USB-interface and as a CSV file on the computer (e.g. with Excel) can be processed further.

In the handheld meter are practical magnets to secure the device to metal surfaces (e.g. flow channel) are integrated. Automatic recognition of the probes, is available. Using the button on the handle, the individual measured values. The Bluetooth handle provides for more comfort for your measurement and less cable clutter in the bag!
