It measures wind speed (0.3–40 m/s) with ±2% accuracy, temperature, relative humidity, and dew point, featuring an 8-shovel sensor for high sensitivity. With USB data logging and PC software, it enables seamless monitoring and analysis. Its portable, rugged design includes a backlit screen, auto shut-off, and tripod mount, making it the ultimate tool for accurate airflow balancing and environmental diagnostics. ## Features - Wind Data Sync on Computer: This wind speed meter can measure wind speed, wind temperature, wind flow, relative humidity (%RH) and dew point and offers max/min of wind speed measurement to compensate for the HVAC system, 8 guide shovels for detection of slow winds up to a resolution of 0.01. Comes with a USB cable and PC software to record, yse and monitor wind data. - [High Accuracy HVAC CFM Meter] Measures a high wind speed range from 0.3 to 40 m/s, +/- 2.0% + 50, display in 6 units: m/s, km/h, ft/min, knots, mph, fpm, wind temperature range 14 F to 140 F, +/- 2.7 F display in 2 units ℃℉ (Celsius) us, Fahrenheit); Wind flow range 0 ~ 999900 ft3/min. - USB data logging with a metal hole in the base so you can mount it on a tripod for hands- operation. Support to connect the wind gauge to the computer via the USB port for monitoring and recording wind speeds, temperature, CFM airflow and RH, perfect for balancing airflow on HVAC tasks such as: Channel Vents, AC Air Performance Testing - Portable wind gauge. It is a portable pocket-sized wind speed meter that comes with a protective case, a large backlit screen, a low battery indicator and an automatic shut-off to save the battery. Portable for indoor and outdoor wind measurements, such as: Long-distance shooting, boat sailing, kite flying, climbing, drone driving, ventilation, turbine air flow testing, etc. - Tips for testing wind temperature %RH The temperature sensors are located in the left and right holes to protect them from sunlight and ensure that the wind reading applies to the air ping through the holes. So without airflow, the temperature and %RH reading will not change quickly, they will change slowly. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B07RXHFF8G | | Best Sellers Rank | 136,612 in Business, Industry & Science (See Top 100 in Business, Industry & Science) 48 in Anemometers | | Brand | BTMETER | | Country Of Origin | China | | Customer Reviews | 3.9 3.9 out of 5 stars (193) 3.9 out of 5 stars | | Item Dimensions | 8.9 x 3.8 x 16.5 centimetres | | Item Weight | 200 Grams | | Manufacturer | BTMETER | | Manufacturer Part Number | Wind Gauge for HVAC CFM Calculation | | Material | Metal Aluminium | | Model Number | BT-866A | | Number Of Items | 1 | | Thread Type | M6 | | Upc | 778469100936 | ## Product Details - **Brand:** BTMETER - **Item dimensions L x W x H:** 8.6 x 3.8 x 16.5 centimetres - **Item weight:** 200 Grams - **Material:** Metal Aluminium - **Number of items:** 1 ## Images ![BTMETER BT-866A Pro Handheld HVAC Anemometer for CFFM Airflow, Wind Speed Meter, Measures Wind Speed, Temperature%RH Dew Point with USB Sync to PC - Image 1](https://m.media-amazon.com/images/I/71T8kC+Hz-S.jpg) ![BTMETER BT-866A Pro Handheld HVAC Anemometer for CFFM Airflow, Wind Speed Meter, Measures Wind Speed, Temperature%RH Dew Point with USB Sync to PC - Image 2](https://m.media-amazon.com/images/I/71cvMCZvcCS.jpg) ![BTMETER BT-866A Pro Handheld HVAC Anemometer for CFFM Airflow, Wind Speed Meter, Measures Wind Speed, Temperature%RH Dew Point with USB Sync to PC - Image 3](https://m.media-amazon.com/images/I/719qdaDyGwL.jpg) ![BTMETER BT-866A Pro Handheld HVAC Anemometer for CFFM Airflow, Wind Speed Meter, Measures Wind Speed, Temperature%RH Dew Point with USB Sync to PC - Image 4](https://m.media-amazon.com/images/I/71gU2G1MpPL.jpg) ![BTMETER BT-866A Pro Handheld HVAC Anemometer for CFFM Airflow, Wind Speed Meter, Measures Wind Speed, Temperature%RH Dew Point with USB Sync to PC - Image 5](https://m.media-amazon.com/images/I/71kdY6jcwZL.jpg) ## Available Options This product comes in different **Colour Name** options. ## Questions & Answers **Q: Does anyone know a link to download the software to us it with a pc? the product comes with a cd but we do not have laptops with cd readers anymore.** A: Hi, thanks for asking.
