Description
The Testo 405i thermal anemometer from the Testo Smart Probes series is a convenient and versatile tool for measuring air velocity, temperature, and volume flows in ventilation ducts. It is designed to be used in conjunction with a smartphone or tablet, offering easy operation and additional features through the testo Smart App.
Here are the key features and advantages of the testo 405i thermal anemometer:
- Measuring Capabilities: The anemometer allows you to determine air velocity, temperature, and volume flows in ventilation ducts. It is also suitable for measuring indoor air velocity, making it useful for locating non-airtight windows. Additionally, when used together with the testo 605i thermohygrometer, it enables the calculation of cooling capacities and heating outputs.
- Smartphone Operation: The testo 405i anemometer utilizes App-based operation, allowing you to view readings conveniently on your smartphone or tablet. This eliminates the need to struggle with reading values from a small display in poorly accessible locations.
- Additional Functions: The testo Smart App provides various practical options. It not only displays measurement data but also evaluates and documents it. You can perform timed and multi-point mean calculations with ease. The App also enables the display of measurement data curves and the sending of measurement data logs as PDF or Excel files.
- Convenient Volume Flow Measurement: With the testo Smart App, volume flow measurement becomes simple. By inputting the duct cross-section intuitively, the App automatically calculates the volume flow, eliminating the need for manual calculations.
- System Requirements: The testo Smart App requires iOS 11 or later for Apple devices and Android 6.0 or later for Android devices. The anemometer connects to your smartphone or tablet via Bluetooth 4.0.
The delivery scope of the testo 405i thermal anemometer includes the anemometer itself, an extendible (400 mm) telescope for reaching distant measurement points, batteries, and a calibration protocol.
The testo 405i thermal anemometer with smartphone operation provides a convenient and efficient solution for measuring air velocity, temperature, and volume flows in ventilation ducts. Its integration with the testo Smart App enhances functionality, data management, and reporting capabilities, making it a valuable tool for professionals in the field.
