About Testo Anemometers
Testo Anemometers are precision instruments designed to accurately measure air velocity, volume flow, and air temperature. Designed for professionals in HVAC, ventilation, and air conditioning systems, these devices play a critical role in ensuring optimal system performance and maintaining good indoor air quality. Testo offers a range of anemometers, including:
- Thermal Anemometers: Also known as hot-wire anemometers, these instruments measure air velocity based on heat loss from a heated sensor element. They are handy for low airflow measurements. Models in this category include the Testo 405i Thermal Anemometer Smart Probe and Testo 425 Digital Hot Wire Anemometer.
- Vane Anemometers: These devices utilise a rotating vane to measure airflow. For example, the Testo 417 Digital Vane Anemometer series has integrated 100mm vanes for air intake and outlet measurements.
- Smartphone-Connected Anemometers: Bluetooth-enabled models such as the 405i and 410i that connect to smartphones, offering advanced data logging and analysis capabilities through the Testo Smart App.
Key Features of Testo Anemometers
- High-Precision Measurements: Deliver precise measurements of flow velocity, volume flow, and temperature, crucial for precise assessments of ventilation grilles and ducts.
- Smart Connectivity: Some models are compatible with the Testo Smart App, enabling real-time data logging, analysis, and a secondary display on your smartphone or tablet.
- Versatile Probes: Instruments like the Testo 416 Vane Anemometer come with telescopic probes extendable up to 850 mm, convenient for reaching into ducts.
- Flow Measurement Capabilities: Equipped to handle both thermal and vane anemometry, providing flexibility in measuring different air flow parameters.
- Accessories for Enhanced Accuracy: Options like flow straighteners and funnel sets improve measurement accuracy, especially in turbulent air flows.
Areas of use include commissioning and balancing of ventilation systems, diagnosing airflow issues in HVAC installations,clean room validation and conducting environmental assessments for indoor air comfort.
