Product Detail

Combined with high quality probes, the Testo 440 dP Air Velocity & IAQ Meter with Differential Pressure Sensor make an efficient solution for the measurement and storage of all air velocity and IAQ parameters. The meter is suited for the automatic simultaneous connection of up to 3 probes: a Bluetooth probe, a wired probe, and a temperature probe with a type K thermocouple connector (probes sold separately). Each meter comes supplied with an integrated differential pressure sensor for filter measurements, fan measurements, optional pitot tube (sold separately) and K factor measurements.
