Testo 440 | Temperature and Humidity kit

Testo 440 | Temperature and Humidity kit

Available to buy the Testo 440 is a practical kit for the measurement of temperature and humidity in a wide range of applications such as indoor air quality studies and in HVAC ductwork systems. The 440 handset is a multifunction measuring instrument which can be used with a number of different optional indoor air quality probes, and the wireless Bluetooth probe can be used to accurately measure temperature & humidity over the range of – 20 to + 70 °C / 5 to 90 % rh, as well as the calculation of dew point, wet bulb temperature and absolute humidity.

Features

• A compact hand-held measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes (optional accessories)
• Clearly structured measurement menus.
• Easy storage and evaluation of measurement data. Measurement data memory for up to 7500 measurement protocols, which can be read via a USB port and further processed as a CSV file on the computer (e.g. with Excel)
• Practical magnets for easy attachment of the measuring instrument to metal surfaces (e.g. ducts)
• Automatic detection of probes, e.g. humidity probe
• Large, backlit colour display
