KEY FEATURES

• 3-in-1 measurement: air velocity, volumetric flow, and temperature
• Telescopic probe extendable up to 300 mm for duct measurements
• Large illuminated, rotatable display for easy reading
• Accurate airflow measurement from 0 to 10 m/s (especially precise at low speeds)
• Volumetric flow calculation up to 99,990 m³/h
• Integrated protective cap shields sensor when not in use
• Compact, lightweight design for portable HVAC use
• Battery-powered operation with long 20-hour runtime

The Testo 405 – Low Cost Thermal Anemometer delivers a highly precise and economical test solution for localized climate comfort studies, draft detection, and ventilation grid cross-balancing updates. Standard vane impellers struggle to register minor air shifts accurately; by incorporating a highly sensitive hot-wire structural sensor chip, the Testo 405 excels at charting subtle indoor currents near drafty windows, structural doorways, or office spaces. Technicians can adapt the swiveling LCD segment layout to match their exact line-of-sight view, eliminating awkward neck angles during high-elevation duct measurements. Providing simple point-of-use evaluation alongside massive volumetric parsing capacity, this handy pocket instrument ensures reliable building comfort compliance validation.

ADDITIONAL FEATURES

• Mechanical rotating protective sensor collar keeps the fragile internal thermal elements safe from heavy dust build-up
• High-resolution 0.01 m/s data increments yield extreme granular accuracy across low-flow environmental matrices
• Lightweight 115 g framework reduces physical operator fatigue during extensive multi-room tracking cycles
• Long 20-hour battery field life matches heavy commercial multi-shift testing and balancing requirements comfortably
• Streamlined structural layout drops securely into tool pouches or standard service uniform pockets for on-the-go checks

APPLICATIONS

• Perfectly optimized for low-velocity draft checking, localized workplace comfort studies, ventilation duct balancing, air register diagnostics, air temperature tracking, and volumetric discharge calculations within commercial and residential HVAC systems.
