The Testo 410i Smart Probe is your go-to wireless vane anemometer for quickly getting accurate air velocity, temperature, and calculated volume flow readings. It's a handy tool for HVAC technicians balancing ventilation systems or checking air outlets without running a bunch of cables.

I've used these on a few tight ceiling plenum jobs where a full-size probe would be a nightmare; the compact size and wireless connection to your phone really save a lot of grief. This little unit makes quick work of airflow measurements for proper system function.

Best For

• HVAC service technicians and installers
• Ventilation system commissioning and balancing teams
• Apprentices learning air flow diagnostics
• Competent DIY owners checking home ventilation performance

Compatibility

The Testo 410i connects wirelessly via Bluetooth 4.2 to your smart device. It requires iOS 13.0 or newer, or Android 8.0 or newer, to run the free Testo Smart App. This app is essential for operation, data display, calculations, and reporting. It also integrates with the MeasureQuick App for live data feeds.

If you're running an older device, check your operating system and Bluetooth version before ordering to ensure full compatibility.

Features

• Measures air velocity, temperature, and automatically calculates volume flow when duct dimensions are entered.
• Compact 30 mm vane diameter ideal for precise readings at air outlets and registers.
• Wireless connection to your smart device via Bluetooth 4.2 for remote operation and data logging.
• Supports timed and multipoint averaging for accurate air flow profiles across a grille.
• Ability to connect and monitor up to six Smart Probes simultaneously for efficient system balancing.
• View measurements as instrument readings, tables, or graphs directly in the Testo Smart App.
• Save and share custom reports as PDF or Excel files directly from your smart device.

Technical Specifications

What's in the Box

• Testo 410i Bluetooth Vane Anemometer
• 3 x AAA Batteries
• Certificate of Conformity

Using It on the Job

1. First up, make sure your smart device has the Testo Smart App installed and Bluetooth enabled. Pop in the 3 x AAA batteries provided.
2. Power on the 410i and connect it via Bluetooth to your Android or iOS device through the app. The connection is usually pretty solid once established.
3. Position the 30mm vane at air outlets, within ductwork, or at registers to take direct velocity and temperature readings.
4. For volume flow, simply enter the duct or register dimensions into the Testo Smart App. It'll do the maths for you on the fly.
5. If you're balancing a multi-outlet system, use timed or multipoint averaging functions. This gives you a more accurate average flow profile rather than just a spot reading.
6. After use, power down the probe and store it safely. A clean vane means accurate readings next time you pull it out.

Limitations & Safety Notes

• This probe requires a compatible smart device (iOS 13.0+, Android 8.0+) with Bluetooth 4.2 for operation.
• Ensure the vane is clear of debris or blockages; any obstruction will affect measurement accuracy.
• Not designed for continuous use in extreme dust or corrosive environments.
• Always follow Australian Safe Work guidance when accessing HVAC systems, especially in confined spaces or at height.

Tradie Pro Tip

When you're trying to get a good volume flow average across a large register, don't just hold it still. Use the timed multipoint averaging in the app to traverse the entire grille evenly. It makes a real difference to accuracy, especially on older, unevenly distributing systems where airflow isn't uniform.

Pair With

This Testo 410i pairs perfectly with other Testo Smart Probes like a Testo 605i humidity and temperature probe or a Testo 549i pressure probe for a comprehensive system diagnostic kit. Consider adding a Testo Smart Case (Climate) to keep all your smart probes organised and protected on the job.
