eA990R Anemometer by ennoLogic – 8 Parameters: Wind Speed, Wind Chill, Air Temperature, Humidity, Heat Index, Dew Point, Barometric Pressure, and Altitude – Digital Weather Meter with Backlight

The Digital Anemometer from ennoLogic eA990R Combines 8 Parameters in one Handheld Instrument.It's like carrying a weather station in your pocket!The digital anemometer eA990R is a feature-loaded little gadget that's perfect for hiking, mountaineering, sailing, golf, hunting, shooting, fishing, flying model planes, quads and drones, or any other outdoor activity. It is an airflow gauge, thermometer, hygrometer, barometer, and altimeter and combines 8 weather parameters into one small light-weight unit. Perfect for your bug out bag. Simply press the power button, hold the anemometer into the wind or air flow you are measuring, and the device instantly starts displaying wind speed in mph. Prefer different units? Press the Units button to cycle through mph, m/s, ft/min, knots, and km/h. Press the Mode button to display other weather parameters - wind chill, air temperature, humidity, heat index, dew point, barometric pressure, and pressure altitude. Pressing the Max button briefly several times cycles through max, min, and average readings since power-on. Press Backlight button to turn the backlight on or off. A long press of the Backlight button freezes the current reading.Specifications:- Wind speed: 0 to 65 mph, resolution 0.2mph, +/-5%- Wind chill: -49 to 50 °F, +/-1.8°F- Temperature: -20 to 158 °F, +/-1.8°F- Relative Humidity: 0 to 100 %, +/-3%- Heat Index: 70 to 130 °F, +/-3.6 °F- Dew Point: -20 to 158 °F, +/-3.6 °F- Barometric Pressure: 0.29 to 32.48 inHg, +/-0.05 inHg - Pressure Altitude: -6000 to 30000 ft, +/-50 ft- Power: Built-in Li-Ion battery, rechargeable via USB. 20 hours typical use.- Size: 4.5” x 1.8” x 1.0”- Weight: 2.5 oz.- Package includes one eA990R, carrying case, lanyard, Micro-USB charging cable and user manual.

• This pocket-sized mobile anemometer measures a lot more than just wind speed: The ennoLogic anemometer eA990R registers wind speed, wind chill, air temperature, humidity, heat index, dew point, barometric pressure, and altitude. With all that it’s hard to believe that this little weather station is smaller than a cell phone and easily fits into your pocket. But it’s main purpose is to deliver accurate wind readings and it does so reliably between 0.4 mph and 65 mph.
• Want to test if it’s safe to fly your drone? Press the power button, hold the anemometer into the wind and within seconds you know the wind speed. Use the Average function to get a more accurate reading in changing conditions, or the Max function to measure gusts. Whether you're flying RC planes, drones, wings, helicopters or quadcopters - this compact ultra-light tool can help you figure out how much headwind you're dealing with, which direction you should launch, or if it's too windy to fly.
• Useful for HVAC DIY work: Measure HVAC register flows in various rooms to help balance out your system. This anemometer does not measure cfm directly, but you can use its Average function and an online conversion tool to estimate cfm from the air speed and size of your register or grille. If your vents are the same size, you can simply use air speed as a comparative relative measurement to balance air flow of your A/C. Or check air speed before and after improvements you made.
• Limitations to be aware of: Temperature response will be slow at zero air flow (about 3 minutes) due to the location of the sensor inside the unit. Altitude is Pressure Altitude, based on barometric pressure. It requires calibration at a known altitude to get true altitude and changes without changing your position if barometric pressure changes.
• Powerful features in a super small package: 8 weather parameters. Multiple units: mph, m/s, ft/min, knots, km/h, °F, °C, %RH, inHg, mbar, hpa, ft, m. Beaufort Scale. Max, Min, Average, and Hold functions. Backlight. 1/4-20 Tripod mount. Built-in Lithium-Ion battery rechargeable via USB. Auto power off with override option. Calibration function. Comes with carrying case, lanyard, Micro-USB charging cable and user manual. 10-year warranty.
