testo 405i – Digital Thermometer for measuring airflow, air velocity, and temperature on air conditioning systems

Measure air velocity, temperature, and volume flow with just one instrument - the durable testo 405i temperature probe provides reliable measurements and, if combined with the smart probe app, allows remote measurement readings. With its automatic calculations, the app erases the need for error-prone manual calculations. Merely download the testo smart probe app, take advantage of user-friendly readings and create custom reports that are quickly saved and retrieved.

The telescopic shaft is extendable and rotatable, making otherwise hardly accessible in-duct measurements of airflow fast and easy. The rugged housing protects the device from impact, making it extremely durable.

Scope of Delivery:

• testo 405i Bluetooth hot-wire anemometer, including 3 AAA batteries and certificate of calibration

• RELIABLE; The hot wire anemometer accurately measures air velocity, temperature and in-duct airflow, as well as volume flow if the duct dimensions are provided
• PRACTICAL; With its hinged, telescopic shaft that can be extended to up to 15", the wind meter can be used to measure airflow even in areas that are difficult to access
• PORTABLE; The compact airflow meter is extremely lightweight and time-saving, making it suitable for personal and professional servicing of air conditioning or HVAC systems
• WIRELESS; Equipped with Bluetooth 4.0, the wind speed meter can easily be connected to a smartphone or tablet and offers remote measurement readings
• SMART; The Smart Probe App for testo gauges hvac provides convenient instrument readings as tables and graphs. All measured data can be stored, retrieved, or included in custom reports
