RS PRO RS-90 Miniature Rotating Vane Anemometer with Bluetooth and Wifi

Introducing the RS PRO mini anemometer. This high-quality rotating vane anemometer has been designed for the measurement of air velocity and air temperature and provides rapid, accurate readings without compromising on quality or performance. The RS-90 is equipped with Bluetooth technology that enables the user to easily transmit measured data and instrument status to a smartphone or Bluetooth-enabled device. The compact anemometer uses a high precision rotating sensor to deliver precise readings, even at low wind speeds, as well as simultaneously measuring the air temperature with the built-in NTC thermistor, making this pocket-sized meter ideal for engineers, service technicians and scientists.

Features and Benefits:

• This RS PRO anemometer has a compact and robust design that offers accurate and reliable results and can be used across a variety of applications
Hand-held wind-speed measurement instrument with user-friendly, easy to use control keys
• Precision air velocity for precision measurement, even at low wind speeds and built-in NTC thermistor sensors that can simultaneously measure air temperature
• Air velocity can be displayed in the following units: m/s, km/h, ft/min, MPH and knots
• Air temperature can be displayed in °C or °F
• Dual-line 4-digit LCD display for easy and clear reading of the measuring data
• Backlight function to enable use in low-light conditions for added versatility
• Bluetooth technology that facilitates easy transfer of measured data to a smartphone or Bluetooth-enabled device for investigation and analysis at a later stage
• This anemometer also features a data hold function
• Auto power-off function after 1 minute and low battery indication assist with battery and power management of the instrument
• Replaceable 9V battery

Applications:

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 and construction
• Sailing, boating and windsurfing
• Climbing and hiking
• Aviation, wind direction, airflow, and gust
• Weather stations and meteorological studies
• Calibration laboratories

Is there a recommended replacement battery?

Yes, the RS PRO anemometer uses a 9V battery for its power supply and replacement battery can be found using RS Stock number 826-4435

What is an anemometer?

An anemometer is a device that has a sensor or sensing unit that is used to measure wind speed and is commonly used to measure and monitor in meteorological applications and much more.
