Testo 405 – Low Cost Thermal Anemometer
The Testo 405 Low Cost Thermal Anemometer is a versatile 3-in-1 instrument for measuring air velocity, volumetric flow, and air temperature with precision and reliability. Ideal for HVAC engineers and technicians, this compact and cost-effective tool simplifies airflow diagnostics in ventilation ducts, air outlets, and indoor environments.
Equipped with a telescopic probe extendable up to 300 mm, the Testo 405 is perfect for accessing hard-to-reach areas inside ducts or vents. The illuminated LCD display can be swiveled for optimal viewing, ensuring convenient operation in all positions.
The device offers excellent accuracy, especially in the 0 to 2 m/s range, making it ideal for detecting low air velocities such as draughts near windows or in workplace comfort studies. For larger systems, the anemometer automatically calculates volumetric flow rates up to 99,990 m³/h for efficient HVAC balancing and verification.
With its rotating sensor protection cap, the Testo 405 is built for durability and longevity, safeguarding sensors from dust and environmental exposure when not in use.
