Testo 417 Digital 100 mm Vane Anemometer with App Connection | Air Velocity, Flow & Temperature Meter

Product Overview

The Testo 417 is a professional digital vane anemometer designed for fast and accurate measurement of air velocity, volumetric flow rate and air temperature. Equipped with a large 100 mm integrated vane, the instrument is particularly suitable for measuring air flow at air inlets and outlets, ventilation grilles, diffusers and HVAC systems.

The Testo 417 combines air-flow measurement with intelligent functions that make HVAC commissioning and inspection work faster and easier. Its integrated vane allows the user to measure the air flow directly at the measurement point, while the instrument can calculate volumetric flow rate and provide time and point averages.

With Bluetooth connectivity, the Testo 417 can be connected to the testo Smart App on a compatible smartphone or tablet. The app provides additional measurement display, configuration, documentation and reporting capabilities.

Its compact handheld design, large display and intuitive operation make the Testo 417 suitable for HVAC technicians, facility managers, ventilation specialists, maintenance professionals and commissioning engineers.

Technical Specifications

100 mm Integrated Vane

The Testo 417 features a large 100 mm integrated vane, making it particularly suitable for measuring airflow at ventilation outlets and grilles.

The large vane captures airflow across a relatively wide area, allowing users to obtain representative measurements without needing a separate probe.

This integrated design also makes the instrument simple to use during HVAC commissioning and inspection work.

Air Velocity Measurement

The Testo 417 measures air velocity from 0.3 to 20 m/s.

Air velocity measurement is useful for:

• HVAC commissioning

• Ventilation system testing

• Air-conditioning inspection

• Supply-air measurements

• Exhaust-air measurements

• Airflow troubleshooting

• Building-service maintenance

The instrument provides a direct digital reading, making it easy for technicians to identify airflow conditions quickly.

Volumetric Flow Measurement

In addition to air velocity, the Testo 417 can determine volumetric flow rate.

The user can enter the relevant duct or outlet dimensions, allowing the instrument to calculate the corresponding airflow volume.

This is particularly useful for checking whether ventilation systems are delivering the required quantity of air.

Air Temperature Measurement

The Testo 417 also measures air temperature from 0 to +50 °C.

This allows technicians to record both airflow and temperature during HVAC inspections without carrying a separate thermometer.

Temperature measurement can be useful for:

• Supply-air checks

• Return-air checks

• Ventilation inspections

• Air-conditioning systems

• Indoor climate assessments

Testo Smart App Connectivity

The Testo 417 features Bluetooth connectivity, allowing it to communicate with the testo Smart App on a compatible mobile device.

Using the app, users can:

• View measurement values

• Configure measurements

• Monitor measurement data

• Display measurement curves

• Save measurement results

• Document measurements

• Create measurement reports

• Manage measurement locations

• Share measurement documentation

This makes the Testo 417 particularly useful for technicians who need to measure, document and report HVAC performance.

Point & Time Averaging

The Testo 417 provides averaging functions that help users obtain more representative airflow measurements.

Point Average

Point averaging can be used when multiple measurement points need to be considered to determine a representative airflow value.

Time Average

Time averaging calculates the average measurement over a selected period.

These functions are particularly useful where airflow is not completely constant.

Min./Max. Function

The Testo 417 can display minimum and maximum measured values.

This allows technicians to identify fluctuations in airflow and temperature during inspections.

Hold Function

The Hold function allows the current measurement value to remain displayed on the screen.

This is useful when the measurement point is difficult to view or when the user needs time to record the measurement.

HVAC & Ventilation Applications

The Testo 417 is designed primarily for professional HVAC and ventilation work.

Air Inlets & Outlets

Measure airflow at ventilation grilles, diffusers and other air outlets.

Supply Air

Check airflow and temperature supplied by HVAC systems.

Exhaust Air

Measure air velocity and airflow volume at exhaust points.

Ventilation Commissioning

Verify whether newly installed or modified ventilation systems are delivering the required airflow.

Maintenance & Troubleshooting

Identify airflow problems caused by blocked filters, incorrect settings or ventilation-system issues.

Building Services

Perform routine measurements as part of HVAC inspection and building maintenance.

Typical Users

The Testo 417 is suitable for:

• HVAC technicians

• HVAC commissioning engineers

• Ventilation specialists

• Facility managers

• Building-services engineers

• Maintenance technicians

• Air-conditioning professionals

• Industrial maintenance teams

• Indoor-air-quality professionals

• Contractors

Compact Professional Design

Despite incorporating a large 100 mm vane, the Testo 417 remains a compact handheld instrument.

Its integrated design eliminates the need to carry a separate vane probe and measuring instrument.

The lightweight construction makes it convenient for technicians who perform measurements at multiple locations during a working day.
