The measurement of all climate parameters with just one measurement device: the multi-function measuring device has a built-in differential pressure sensor and intuitive operation with clearly structured measurement menus. Set the ventilation and air-conditioning systems, the monitoring of air quality and comfort measurements - there is a wide range of combination possibilities when used with high-quality, digital probes that are perfect for your measuring task. Probes not included.
The testo 440 dP climate meter includes a differential pressure sensor, USB cable and calibration protocol, with batteries and is immediately ready for use.
The meter has a large, illuminated colour display and has a structured measurement menu activated by pressing. Specific temporal averaging, average volume flow, current measured value, as well as min/max values are displayed. The dimension and geometry of the channel cross-section must be entered to obtain an exact calculation of the volume flow. Other measurement menus, such 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 for up to 7,500 measurement protocols in its integrated measurement data memory.
