Brand: Testo
Model: 0560 4402
Products Description:
Use the testo 440 dP air velocity and IAQ measuring instrument in combination with the high-quality, digital 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.
A differential pressure sensor is already integrated in the testo 440 dP. This makes it possible to carry out measurements on filters and fans, as well as Pitot tube and K-factor measurements (please order Pitot tube separately).
Product Features:
Ø Intuitive: clearly structured measurement menus for volume flow, K-factor, degree of turbulence, cooling/heating output, mould detection and long-term measurement, such as CO₂
Ø Wireless: Bluetooth® probes for extra convenience when measuring and less cable clutter in the measuring case (please order probes separately)
Ø Clear and reliable: large graphic display with parallel display of 3 readings as well as internal data storage and USB port for data export
Ø Includes a differential pressure sensor: for Pitot tube measurement and monitoring filters
