What makes the HP-866B-WM different from a basic wind meter?

Along with wind speed and air temperature, it provides relative humidity, dew point, barometric pressure, pressure-based altitude and wind chill—giving you more environmental information in one handheld tool.

Can I use this anemometer for HVAC checks and CFM calculations?

Yes. Compare air velocity at HVAC vents, duct openings and exhaust fans. To calculate CFM manually, multiply average air velocity in ft/min by the opening area in square feet.

How does it help me check changing outdoor wind?

View current wind speed or switch to MAX, MIN and AVG to compare peaks, lows and averages. Choose mph, m/s, km/h, ft/min or knots for ventilation checks, sailing, drone outings and other outdoor activities.

Can I read the screen in low light, and are the controls easy to use?

The backlit LCD helps you read measurements in dim spaces or after sunset. Dedicated buttons switch measurement views and units. Press and hold Mode for more than 3 seconds to turn the backlight on or off.

Does it track pressure changes, and is the altitude GPS-based?

Review 16 pressure records taken at two-hour intervals. Altitude is calculated from air pressure, not GPS, so weather changes can affect the reading. The meter also allows pressure calibration.
