Editor's Notes

April 15, 2019:

A hotwire anemometer is a useful tool when you're carrying out surveys of HVAC systems, as well as for environmental monitoring and other projects involving the measurement of air flow velocity. The telescoping probe is convenient for inserting into ductwork for easy, quick readings.

Look to the Fieldpiece STA2 as a durable choice thoughtfully designed to be hung magnetically, so you don’t need to hold the meter while you’re busy testing. The flattened edges of the probe make it easy to hold it the correct way, for accurate readings.

If you prefer to see your results on your smartphone via a downloadable app, consider the Testo 405i, which consists of just a slim handle and the probe. The rest featured here all come with built-in LCD screens, but some provide a handy port for transferring data to your PC. These include the Extech 407123, TPI 565C1, and the Amprobe TMA-21HW. No matter which you ultimately choose, all of the models here are designed to provide accurate, quick results.
