testo 440 dP – Multi-instrument for ventilation \/ indoor climate with differential pressure<\/h2>\n

Use the testo 440 dP airflow and indoor climate meter in combination with high-quality sensors (and also testo SmartProbes) to measure and save all ventilation and indoor climate parameters (sensors ordered separately). Up to 3 sensors can be connected simultaneously: a Bluetooth sensor, a cable sensor and a temperature sensor with thermocouple connector type K. Thanks to automatic sensor detection and clearly structured measurement menus, the instrument is very easy to use and will make your daily measurement tasks much easier.<\/p>\n

The testo 440 dP already has an integrated differential pressure sensor.<\/strong> It allows you to perform measurements on filters and fans, as well as with pitot tubes (prandtl tubes) and with K-factor (measuring hook ordered separately).<\/p>\n

Measure with just a few clicks
\n Measuring<\/strong>should be quick and easy – the testo 440 airflow and indoor climate meter automatically recognizes all connected sensors. This means that you never have to manually reset any measurement parameters when switching to another sensor. Clearly structured measurement menus for duct\/vent volume flow, k-factor, turbulence degree, cooling\/heating load, moisture damage risk indication and logging function. These menus allow you to complete measurement tasks faster, more efficiently and more reliably. Reports can be exported as Excel files via the USB interface or printed on site.<\/p>\n

Wireless and compact – more applications, less equipment
\n<\/strong>Highly versatile: with a universal handle that can be connected to any transducer, you can handle more applications with less equipment, while taking up more space in your toolbox.
\nThe Bluetooth handle can transmit readings up to 20 meters, eliminating cable clutter and freeing up space in your toolbox. As a practical option, a cable handle is also available. This is a big advantage if Bluetooth signals are not allowed.<\/p>\n

Practical data management
\n<\/strong>The multi-instrument can store up to a maximum of 7,500 measurement blocks which can be read out via a USB port and further processed as a CSV file on your computer (e.g. with Excel). With the Testo BLUETOOTH\/IRDA printer (ordered separately), you can print a report with your measurement data directly on site.<\/p>\n

Intelligent calibration concept for maximum accuracy
\n<\/strong>You can rely on accurate measurement results when using our digital sensors, as the measurement uncertainty in the instrument is now eliminated. You only need to send in the sensor part for calibration and continue using the multi-instrument itself.<\/p>\n
