Testo 440 Air Velocity and IAQ Measuring Instrument

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 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 structured measurement menus guarantees simple operation that makes day-to-day work easier.

Intuitive, structured measurement menus cover volume flow, degree of turbulence, cooling and heating output, mould detection and long-term measurement such as CO₂, so a single instrument supports a wide range of HVAC and IAQ tasks. Its compact, robust design and clear display make it a practical everyday companion for ventilation and air-conditioning professionals.
