TESTO 405i Hot-Wire Thermal Anemometer | Smart Probe Data Logger

The Ultimate Smart Probe for HVAC Air Flow Analysis in Sri Lanka

The TESTO 405i is a revolutionary hot-wire thermal anemometer from the Testo Smart Probe series, designed to bring professional air velocity, volume flow, and temperature measurement directly to your smartphone. This probe-only instrument eliminates the need for a separate display, offering unmatched portability and convenience for HVAC technicians, engineers, and facility managers across Sri Lanka. Its extendable telescopic shaft makes it the perfect tool for precise in-duct measurements.

By combining a high-precision thermal sensor with the power of the Testo Smart App, the 405i transforms your mobile device into a powerful command center. It functions as a complete air flow meter and data logger, allowing you to not only view live readings but also to configure measurements, analyze data trends, and generate professional reports on-site. For a smarter, faster, and more efficient workflow, the TESTO 405i is the modern solution.

Key Features of this Hot-Wire Anemometer Smart Probe

Professional Smart Probe Design: As a probe-only instrument, the 405i is ultra-compact and cable-free. It connects wirelessly via Bluetooth to your smartphone or tablet, reducing clutter and making measurements in tight spaces effortless.
App-Based Data Logger & On-Site Reporting: The Testo Smart App acts as a powerful data logger, allowing you to store complete measurement series as a timed graph or table. Finalize your work by adding photos and comments, and send a professional PDF report directly from the job site.
Telescopic Probe for In-Duct Measurement: The slim, telescopic probe extends up to 400 mm, making it easy to reach the center of ventilation ducts for accurate air velocity and flow profile measurements.
Accurate Flow & Temperature Measurement: The sensitive hot-wire sensor provides reliable and precise readings of air velocity and temperature, especially at low flow rates, which is critical for IAQ and comfort-level assessments.
Automatic Volume Flow Calculation: The app automatically calculates the total volume flow (CFM/CMM) after you easily input the duct dimensions, simplifying system performance diagnostics and air balancing tasks.

Common Applications

This smart air flow data logger is essential for:

In-Duct & Ventilation Grille Measurements: Perfect for determining air velocity, temperature, and volume flow inside ventilation ducts and at supply/return grilles to ensure proper system function.
HVAC System Balancing & Diagnostics: Quickly check and document the performance of heating, ventilation, and air conditioning systems to optimize efficiency and ensure occupant comfort.
Troubleshooting Air Flow Issues: Identify areas of poor ventilation or drafts by comparing volume flows in different rooms or checking for leaks in ductwork with high precision.
