Product Description

What is digital anemometer BT-100?

The BTMETER handheld anemometro BT-100 is a wind speed measurement device that can measure air flow velocity from 59~5905 ft/min with 5% high accuracy, test wind temperature 14℉~113℉ with ±3.6℉accuracy.

What can the BT-100 handheld air flow meter do?

It can monitor wind speed for HVAC system to assess its cooling and heating efficiency, balance air vent flow, troubleshoot dust collector issues, and also test wind speed for wind-related activities such as drone driving, shooting, hunting etc.

What is the measurement range and resolution of this digital anemometer BT-100?

The BTMETER anemometer BT-100 can measure wind speeds in 5 units, each with different resolutions: 0.3-30 m/s (0.1 resolution), 59-5905 ft/min (19 resolution), 1-55 knots (0.2 resolution), 2-90 km/h (0.3 resolution), and 1-65 mph (0.2 resolution)

Can this be used to measure cfm going to hvac air handler at inlet filter?

Yes, you can use it to detect hvac air vent wind situation. But please noted that it can't directly display CFM airflow volume reading - manual calculation will be required to get this. FYI, Air Flow CFM(Q)=Wind speed(V) xDuct Cross Sectional Area(A)

How much does this windometer weigh?

The BTMETER airflow tester BT-100 has a weight of approximately 155g and a compact handheld size of 165 x 85 x 38mm

Great for measuring HVAC vent flow (CFM); temperature sensor needs 3 min to show accurate temp
4 Stars
Great for measuring HVAC vent flow (CFM); temperature sensor needs 3 min to show accurate temp
Whatever your believe on climate trends, HVAC is increasingly important these days - and this inexpensive tool is what regular people like you and me need for PROVING what the airflow and temp is coming out of our vents when the HVAC techs (or property owners) say "it's working as designed."Use it to measure airflow somewhere you know the HVAC works well, and then compare those measures against your own system to see the deltas in CFM (Cubic Ft per Minute of airflow) which then arms you to press the HVAC firm or property owner into making your place comfortable.Helps to use a dB meter (even just a phone app) to measure acoustics of system on/off (to properly size the ducting), and an infrared/laser pyrometer for quicker temp measure of the vent surface (also super handy for measuring cooking surfaces, tire temps at the track...)The device is borderline 5 stars (I gave it benefit of the doubt) because its temp readout takes 3-4 minutes at a location to accurately read the temp vs. the laser pyrometer I pointed at the vent to get a baseline temp reading. Otherwise it's been a strong 5-star experience, seems like a quality design that should last a long time.
