Testo 405 Thermal Anemometer

Overview

The Testo 405 is a compact, pocket-sized thermal anemometer designed for quick, reliable air velocity and temperature measurement in ventilation ducts. Thanks to its telescopic hot wire probe, it can be inserted directly into a duct to measure air velocity, temperature and volume flow, and it is equally useful for checking indoor air movement.

With a wide measuring range, fine 0.01 m/s resolution and volume flow calculation up to 99,990 m³/h, the testo 405 covers the everyday needs of HVAC technicians. Its slim design allows one-handed operation, and simple battery power keeps it ready to use whenever an airflow check is needed.
