Rotating vane anemometers are used to measure environmental conditions quickly and accurately. The information and data they provide are vital in a wide range of applications and environments. They are essential for reporting, forecasting and planning and more importantly health and safety. Some of the more common applications are

• HVAC system performance
• Building and construction
• Environmental testing
• Clean rooms
• Fans / motors / blowers
• Meteorological studies
• Wind direction, wind speed and gust

Q – Are there any additional accessories available?
A- Yes, the testovent 417 funnel set is available separately. It can be used in conjunction with the 417 digital anemometers for measuring the volume of flow at ventilation grilles and plate outlets quickly and conveniently. See part number 516-0602
Q - Is there a recommended replacement battery?
A - Yes, the RS PRO anemometer uses a 9V battery for its power supply. See RS part number 826-4435

9V PP3 battery, integral 100mm vane with temperature sensor and instructions.

Measure airflow, wind speed and air temperature with this Testo vane anemometer. The component's sensitive probe tests the air and transmits the information along the cable to the console. It then converts the electrical reading into metres per second (m/s) and degrees centigrade (°C) and displays the numbers on the screen for fast results that are easy to understand. The display has an LED (light-emitting diode) backlight to make sure it's visible even in dark areas.

• Offers air velocity resolution within 0.01m/s (metres per second) for precise measurements
• 9V battery offers a 50-hour lifespan for long-lasting use
• Auto-off feature helps preserve battery power when not in use
• Maximum air velocity of 20m/s for use in fresh gales and below
• Wide operating temperature range of 0°C to +50°C for use in demanding environments

• Heating applications
• Roofing
• Weather forecasts
• Vent installation

This anemometer has a robust ABS (acrylonitrile butadiene styrene) housing that's impact-resistant and protects the internal computer from damage.
