Testo 440 dP Air Velocity and IAQ Measuring Instrument

Overview

Use the Testo 440 dP anemometer and IAQ meter in combination with a high-quality digital probe to measure and record all air velocity and indoor air quality parameters (probes ordered separately). Up to three probes can be connected simultaneously — a Bluetooth® probe, a wired probe and a temperature probe with a Type K thermocouple connector — and automatic probe detection with a clearly structured measurement menu guarantees simple operation that facilitates your daily work.

A differential pressure sensor is incorporated in the testo 440 dP. This enables measurements on filters and fans, as well as K-factor measurements and pitot-tube measurements (pitot tubes ordered separately). The result is a single, versatile instrument for airflow, IAQ and pressure work in ventilation and air-conditioning systems.
