H HOLDPEAK 866B Handheld Digital Anemometer — Eight-Vane Wind Speed Meter, Dual Temp & CFM for HVAC (Compact, Tripod Mount)

The HoldPeak 866B is a compact handheld digital anemometer for fast, reliable wind-speed, temperature and CFM measurements in the field.

Designed for outdoor and HVAC use, the H HOLDPEAK 866B combines a small-footprint housing with an eight-vane rotor and dual temperature sensors to capture breeze strength, air temperature and wind chill. The unit displays readings in multiple units, stores max/min/average values, and fits into a waterproof carry pouch for transport. It pairs practical features—backlight, auto-off and tripod mounting—with a lightweight build so you can measure conditions on-site without bulky equipment.

How precise is this anemometer when checking wind speed?

The 866B uses an eight-blade impeller and a smooth shaft to reduce friction and stabilize readings, providing accurate wind speed detection across a broad range. Its calibration aims to keep typical deviation low so you can trust readings for both gentle breezes and stronger gusts.

• Measurement range covers very low to high wind speeds for site surveys
• Reported tolerance typically close to industry norms for handheld meters
• Dual temperature sensors improve wind-chill and temperature consistency

What measurement options and functions does it include?

The device offers multiple units for wind speed and temperature, plus statistics and conveniences that speed up field work. Use the max/min/average memory and unit-switching to match your project or regional preferences.

• Switchable wind units: m/s, km/h, ft/min, knots, mph
• Temperature in °C or °F and wind-chill readout
• Max/Min/Average memory, backlight, battery level indicator, and auto-off

Can I mount or carry it safely during outdoor activities?

The 866B includes practical mounting and protection options so you can keep hands free or safeguard the meter during transport. A tripod thread lets you fix the meter for steady monitoring, while the supplied pouch and wrist strap reduce the chance of loss or drops.

• Standard tripod hole for stable, hands-free measurements
• Durable hand strap prevents accidental drops while in use
• Water-resistant carrying pouch protects the meter on the move

How does it help with HVAC and CFM calculations?

The anemometer provides the wind-speed input needed to estimate airflow through ducts and vents, making it useful for basic HVAC checks and CFM approximations. With a measured wind speed and a known duct cross-sectional area, you can calculate airflow using the standard CFM formula.

• Senses low airflows suitable for duct and vent testing
• Use measured speed × duct area to estimate CFM
• Portable form factor speeds spot checks and maintenance rounds

Who is this for? The HoldPeak 866B is well suited for hobbyists and pros who need a portable, versatile wind meter: drone pilots, sailors, kiteboarders, outdoor sports enthusiasts, HVAC technicians doing quick duct checks, and anyone who needs on-the-spot wind and temperature data without hauling heavy instruments. The included batteries, screwdriver and carry pouch make it ready for immediate use straight from the box.
