Description
xThe HoldPeak 866B is a compact handheld digital anemometer that precisely measures wind speed, temperature and helps calculate CFM for outdoor and HVAC use.
Built for hikers, drone pilots, HVAC technicians and outdoor sports enthusiasts, the HoldPeak 866B combines an eight-vane sensor, dual temperature sensing and easy-to-read digital reporting in a lightweight package. Its broad unit options, tripod-mount capability and protective carrying pouch make it a practical instrument for field work, hobby projects and basic airflow diagnostics.
How accurate and sensitive is this anemometer?
The 866B delivers reliable readings across a practical range, detecting speeds from 0.67 to 67.1 mph with a quoted tolerance around ±2% of readings. The eight-vane rotor and smooth shaft reduce measurement noise, while dual temperature sensors stabilize wind-chill and air temperature reporting.
- Wind speed range: 0.67–67.1 mph (multiple units selectable).
- Precision: approximately ±2% across the range for consistent results.
- Sensors: 8 vanes and dual temp sensors for stable measurements.
- Hardware: smooth fan shaft to minimize mechanical friction and jitter.
What measurement modes and units does it support?
The HoldPeak 866B offers flexible display options to suit different applications: switchable wind speed units, temperature units, and summary statistics such as max, min and average. These modes make it easy to log short-term gusts or steady airflow for CFM calculations.
- Wind speed units: m/s, km/h, ft/min, knots, mph.
- Temperature units: °C and °F selectable on demand.
- Data modes: Max, Min and Average wind speed readouts.
- Extras: battery level indicator, auto-off and backlight for low-light use.
Can I use the 866B for HVAC and CFM calculations?
Yes — the 866B can be used to estimate airflow (CFM) when paired with a duct cross-sectional area. It detects low airflows typical in vents and ducts, providing a quick field reference for installations and troubleshooting without complex equipment.
- CFM calculation: Air Flow (CFM) = wind speed × duct cross-sectional area.
- Low-flow sensitivity for vent and duct checks during HVAC work.
- Portable format for quick spot checks without hauling larger gear.
- Tripod mount option stabilizes the unit for steady long-read measurements.
What accessories and practical features come with the device?
The 866B arrives ready for field use: batteries, a waterproof carry pouch and a hand strap keep the meter protected and handy. A tripod hole and included screwdriver let you mount or secure the anemometer for repeatable measurements during tests or outdoor sessions.
- Included: HoldPeak 866B unit, 2× AAA batteries, user manual and screwdriver.
- Carrying pouch: splash-resistant storage for outdoor travel and protection.
- Mounting: tripod hole for fixed-position measurement and stability.
- Handling: hand strap to prevent accidental drops during use.
Who is this for? The HoldPeak 866B suits a wide set of users who need dependable, portable wind and airflow readings: hobbyists flying drones or kites, sailors and surfers checking conditions, golfers and outdoor athletes assessing wind, and technicians performing HVAC spot checks or simple CFM estimates. If you want a lightweight, multifunction meter with clear reporting and practical field accessories, the 866B is designed to be a straightforward, cost-effective tool.
FAQ
Q: What wind speed range does the HoldPeak 866B measure?
A: It measures from 0.67 to 67.1 mph and offers multiple unit options like m/s, km/h, knots and ft/min.
Q: Can I use the 866B for CFM calculations?
A: Yes. Use measured wind speed multiplied by the duct cross-sectional area to estimate CFM for basic airflow checks.
