Five handheld anemometers compared on what their makers publish: simple wind meters, HVAC airflow meters with CFM, a wind-plus-weather meter and a Kestrel for shooters.
How to measure wind speed with a handheld anemometer or weather station: where to stand, how to hold it, averages vs gusts, height, units and the Beaufort scale.
Three BTMETER anemometers you can switch between on one Amazon page. The BT-100 basics, the BT-100APP Bluetooth app, and the BT-100WM with humidity, pressure and altitude.
Most handheld anemometers show air speed, not CFM. The formula, duct area for square and round ducts, worked examples, unit conversions and the limits.
The BTMETER BT-100 anemometer manual in plain English: the six buttons, switching units, MAX/MIN, the 15-second average, wind chill and full specs.
FosPower A1 or Midland ER40? Both crank, solar and USB radios with a flashlight, but only one sounds NOAA alerts. Side by side from the makers' documents.
The FosPower A1 stores 2,000 mAh but its USB port is rated at 750 mAh. What that means for your phone, how slow solar is, and how to make it last.
The FosPower A1 emergency radio manual in plain English: the parts, tuning the weather band, four ways to charge, charging your phone and quick fixes.
Three weather stations without Wi-Fi, side by side: which one measures wind and rain, which has sensor screens, what each listing leaves out, and which suits your home.
The Brataste 7.5-inch weather station: what it measures, how to keep the screen on (Night Mode), why it flickers, how long the forecast takes, and what the listing leaves out.
