Testo 440 – Air velocity And IAQ Measuring Instrument

Order-Nr. 0560 4401

Use the testo 440 air velocity and IAQ measuring instrument in combination with high-quality probes to measure and store all air velocity and IAQ parameters (please order probes separately). Up to 3 probes can be connected simultaneously: a Bluetooth probe, a wired probe, and a temperature probe with a type K thermocouple connector. Automatic probe detection and clearly structured measurement menus guarantee simple operation and will make your day-to-day work easier.

• Intuitive: clearly structured measurement menus for volume flow, degree of turbulence, cooling/heating output, mold detection, and long-term measurement, such as CO₂
• Wireless: Bluetooth® probes for extra convenience when measuring and less cable clutter in the measuring case (please order probes separately)
• Clear overview: large graphic display with parallel display of 3 readings
• Safe and reliable: internal data storage and USB port for data export

Measure in just a few clicks with the testo-440 multifunction measuring instrument

Take your measurements quickly and easily: the air velocity and the IAQ gauge automatically detect each connected probe. This means there is no need to manually reset parameters when changing transducers. Well-structured measurement menus for in-duct/outlet volume flow measurement, funnel measurement, turbulence measurement, cooling/heating capacity determination, mold detection, and long-term measurement give you the ultimate support throughout your daily life. Daily work.
