PCE-VA 20 is a multifunction anemometer for assessing wind, weather, indoor / outdoor environmental climate conditions as well as for testing heating, ventilation and air conditioning or cooling (HVAC) systems. This combination anemometer-hygrometer-thermometer features a 10 cm / 3.9" Ø fan impeller, easy-to-read backlit LCD, and functions such as display hold, average value, maximum value, minimum value, battery-saving automatic power off, low-battery indicator, and metric or imperial unit selection.

• Measures air flow velocity, volume flow, relative humidity, air temperature, dew  point temperature and wet-bulb temperature
• Air flow velocity range: 0.2 … 30 m/s (39.4 … 5905.5 fpm)
• Accuracy: ±(1.5% of measured value + 0.3 m/s) when less than 20 m/s, ±(3% of  measured value + 0.3 m/s) when more than 20 m/s
• Resolution: 0.1

This anemometer station with outside sensor is a real all-rounder. The wireless anemometer station with outside sensor is easy to assemble based on the instructions provided. You do not have to be a professional to operate the wireless anemometer station and outside sensors. The weather data of the anemometer station with outside sensor for different parameters are sent up to 100 meters by radio signal to the main station.

The hot wire anemometer measures the flow velocity according to the hot wire principle. This guarantees a particularly compact design. In addition to the flow rate, the hot wire anemometer can measure the volume flow and the ambient temperature.

• Measuring range: 0.3 … 30.0 m/s / 0.98 … 98.4 ft/s
• Probe length: 270 … 990 mm / 10.63 … 38.98 / 29.1"
• Probe diameter: Ø0.8 … 1.2 mm / 0.031 x 0.047"
• Data memory for 960 measured values
• Wind speed
• Volume flow
• Temperature measurement

This vane anemometer is used to measure air speed, air flow, air temperature and infrared (IR) temperature. This multi-functional portable handheld vane anemometer offers a quick response time, allowing for real-time measurement. In addition, the impeller features a thread for mounting in one location for fixed measurement.

• Air speed range: 0.4 … 30 m/s / 0.9 … 67 mph
• Air flow range: 0 … 9999 CFM / CMM
• Air temperature range: -10 … 60°C / 14 … 140°F
• IR temperature range: -50 … 500°C / -58 … 932°F

The multifunction anemometer determines the wind speed via an impeller with a diameter of 65 mm. The anemometer can reliably determine the speed in a measuring range of 0.3 … 45.0 m/s.

• Measuring range: 0.3 … 45.0 m/s / 0.9 … 147 ft/s
• Velocity and volume flow measurement
• Telescopic probe with a length of 270 … 540 mm / 10.63 … 21.26“
• Impeller opening of 65 mm / 2.5"
• Interface: Micro USB
• Data memory: 960 measured values

Without a doubt, the main advantage of this handheld cup vane anemometer is that it doesn't need to be held exactly in the direction of the wind. Anemometer with impellers typically have to be held exactly in the direction of the air flow to take accurate measurements. Digital cup vane anemometer, wind direction will not influence the measurement.

• 0.9 to 35.0 m/s
• 2.5 to 126.0 km/h
• 1.4 to 68.0 knots
• 1.6 to 78.2 miles/h
