Testo 405 Pocket Sized Thermal Anemometer

Description

The Testo 405 is a pocket-sized thermal anemometer used to measure air velocity, volume flow, and temperature. As a thermal or hot-wire anemometer, it uses heated sensor technology, making it particularly precise for measuring low air velocities. It is designed for use in quick check measurements in ventilation ducts and for assessing indoor air quality.

Key Features

• Extendable telescope: The probe features a telescopic shaft that extends up to 300 mm (11.8 in), making it easy to access measurement points inside ventilation ducts or other hard-to-reach areas.
• Rotatable display: The illuminated display can be swiveled into various positions, allowing for convenient reading of measurement values from different angles.
• Sensor protection: A rotating protective cap guards the hot-wire sensor from mechanical stress when the instrument is not in use, increasing its longevity.
• Duct bracket: An included bracket provides a practical way to position the probe optimally in a duct to achieve stable and accurate measurement results.
• Measures low air velocities: The Testo 405 is highly sensitive and accurate in the low-velocity range of 0 to 2 m/s, making it suitable for checking for draughts at windows and other indoor air quality assessments.
• Volume flow calculation: After entering the duct cross-section area, the anemometer automatically calculates and displays the volumetric flow.
• Easy to use: With only a single control button for operation, the device is simple and quick to use.
