Testo 425 Digital Hot Wire Anemometer with App Connection

Description

The Testo 425 Digital Hot Wire Anemometer with App Connection is a thermal anemometer designed for measuring flow velocity, volume flow, and temperature in HVAC systems. It is particularly effective for low air velocities, and its integrated telescopic probe, which extends up to 820 mm, makes it ideal for measurements in large or difficult-to-access ventilation ducts.

Key Features

• Highly sensitive thermal sensor: Provides precise measurements, especially for very low air velocities.
• App integration: Wirelessly connects via Bluetooth to the Testo Smart App on your smartphone or tablet. The app provides a second display for readings, enables in-app configuration, and stores measurement data and graphs.
• Telescopic probe: The cable-connected thermal probe extends up to 820 mm (approximately 32 inches), allowing you to take measurements overhead or deep inside large ducts.
• Automatic calculations: The anemometer automatically calculates volume flow when the duct cross-section area is entered and can perform timed and multi-point averaging for accurate results.
• Efficient documentation: The Testo Smart App makes it easy to document and archive measurement results, with options to export data as PDF or Excel files via email.
• Hold function: The instrument has a hold function to freeze the current reading for easy comparison.
• Durable construction: A robust housing ensures the device is durable enough for professional use in demanding field conditions.
