Product Description

The DWYER 471B-1 is a hot wire air velocity meter with a digital LCD display and a stainless steel probe. It measures velocities under 100 fpm up to 4,000 to 6,000 fpm, with a temperature accuracy of +/- 1.5%. Powered by battery, this unit does not include data logging.

Frequently Asked Questions

What is the DWYER 471B-1 hot wire anemometer used for?

The DWYER 471B-1 hot wire anemometer measures low air velocity and temperature in HVAC systems, cleanrooms, and industrial ventilation. It is ideal for balancing ducts, monitoring fume hoods, and verifying airflow in environments requiring precise readings under 100 fpm up to 4,000–6,000 fpm.

What are the specifications of the DWYER 471B-1?

The DWYER 471B-1 is a digital hot wire anemometer with an LCD display and stainless steel probe. It measures air velocity from under 100 fpm to 4,000–6,000 fpm, with temperature accuracy of +/- 1.5%. It is battery-powered, has no data logging, and includes a stainless steel vane.

Where to buy the DWYER 471B-1 worldwide?

You can source the DWYER 471B-1 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine Dwyer instruments for HVAC and industrial applications.

How to use the DWYER 471B-1 hot wire anemometer?

To use the DWYER 471B-1, insert the stainless steel probe into the airflow, ensuring the sensor is perpendicular to the flow direction. Power on the unit and read velocity and temperature on the LCD. Avoid touching the hot wire element and calibrate per Dwyer's manual for accurate readings under 100 fpm.
