Testo-440-dP-Air-velocity-and-IAQ-Measuring-Instrument

Model No :

Testo 440 dP - Air velocity and IAQ

Part Code :

0560 4402

Overview

Testo 440 dP can be used for 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.

Features

- 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
- Wireless: Bluetooth® probes for extra convenience when measuring and less cable clutter in the measuring case (please order probes separately)
- Clear and reliable: large graphic display with parallel display of 3 readings as well as internal data storage and USB port for data export
- Includes a differential pressure sensor: for Pitot tube measurement and monitoring filters

Major Applications

- Long-term monitoring of indoor air quality
- Convenience and maximum flexibility for duct and outlet measurements
