Today we will be reviewing the Dwyer 473B-1 Vane Thermo-Anemometer. The Dwyer 473B-1 is a versatile tool that’s affordable as well.

The Dwyer 473B-1’s main appeal is its ability to easily and quickly measure velocity, air temperature, volumetric air flow, and humidity all at the same time. The Dwyer 473B-1 essentially combines four tools into one, making it the “Swiss army knife” of HVAC testing technology. The Dwyer 473B-1 is compatible with a variety of Dwyer’s other probes, but comes with Dwyer’s VP1 100mm vane thermo-anemometer. The Dwyer 473B-1 can read temperatures from -40 to 212°F. It can process air velocity at temperatures between -20 to 212°F, and measure up to 6000FPM with the included VP1 thermo-anemometer. The Dwyer 473B-1 is rugged and is built to be able to handle itself in any condition. It has an extruded aluminum housing which keeps it lightweight but sturdy, and a digital LCD display that allows you to see in dark or bright conditions. The Dwyer 473B-1 also has the ability to datalog up to 99 different readings.

The Dwyer 473B-1 is great for any technician that wants to minimize the number of tools for the job. It’s great for HVAC inspections and residential balancing. Does anyone else like products that can test for multiple factors?
