Testo 440 dP Multifunction Climate Meter

The Testo 440 dP Multifunction Climate Meter is a versatile instrument intended to perform all manner of environmental measurements. It can work with a vast array of wired or wireless probes (not included) in order to measure parameters such as air temperature, carbon monoxide, humidity, carbon dioxide, air flow velocity, and light concentration. A universal probe connection enables quick interchange of probes. The meter also has an internal sensor that can measure differential pressure from -150mbar to 150mbar.

The internal software on the Testo 440 dP allows it to use measurements from different probes to calculate various additional values including wet bulb, dew point and volume flow as well as detecting mould-friendly conditions. The differential pressure measurement function also enables measurement of K factor, pitot tube measurements and measurement at filters.

A set of intuitive menus can be accessed via the Testo 440’s vibrant colour screen and are very easy to navigate using the simple push-button interface. The illuminated colour display can show up to three readings simultaneously and clearly displays all parameters to a high degree of precision.

The datalogging function saves up to 7500 readings to the Testo 440’s large onboard memory and a USB cable allows the user to export files to a PC in Excel format and it is capable of working with an optional on-site printer to produce instant hard copies.
