Description

The Testo thermal velocity hot wire probe provides a versatile solution for measuring air movement in ventilation systems. This multifunctional tool allows you to determine both flow velocity and volume flow within ventilation ducts or at various ventilation outlets. It is designed to handle low and medium flow velocities up to +20m/s, making it an essential tool for HVAC inspections. Beyond airflow, this probe simplifies your workflow by measuring temperature and humidity simultaneously. The integrated telescope extends up to a maximum length of 745mm, providing the reach needed for deep duct access. With a 12mm probe head diameter, it is specifically sized for efficient use in ventilation ducts, ensuring accurate data collection in professional environments.
