Features:
- Intuitive: clearly structured measurement menus for volume flow, degree of turbulence, cooling/heating output, mould 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
Application/s:
- Duct and outlet measurements
- Indoor air quality
- Turbulence measurement
- Cleanrooms and laboratories
Overview:
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 type K thermocouple connector. Automatic probe detection and clearly structured measurement menus guarantee simple operation and will make your day-to-day work easier.
