Fieldpiece STA2 in-Duct Hot Wire Anemometer for HVAC Airflow Measurement - CFM, Air Velocity & Temperature - 38" Telescoping Probe - Hands-Free Air Balancing Tool

Works for those hard to get to grilles and low flow applications. Very accurate and especially helpful on smaller grilles as well as min split ac units with supply/return that you can not use a balancing hood on

Really great tool super happy!!!!

First time I use this field piece tool, I’m not gonna lie at the beginning I was little bit confuse but after I figure out on how to measure cfm I was impressed on how accurate and how simple is it to use!! Worth the money I paid !! I wish I had known before about this tool

The instrument is extremely easy to use, comes in a solid case. Magnet adds to convenience and the flow calculation feature is simple to setup and is a massive advancement over just having velocity measurement. I wish that I'd bought one of these years ago.

After learning how to properly use the tool, I was able to offer better results for my service calls.

working really well and like all the other items i have had from them flawless

Truly amazing technology. If you are an HVAC tech then you need this. just tell it the duct size and it does the rest. OK its not as accurate as a flow hood, but the convenience is way better. It's still probably accurate enough to be 90% within range.

Quality instrument

Easy to use with little set up time. Great for recording trends and troubleshooting ventilation systems.

We use this product for our HVAC balancing and testing. I am very impressed with the product and the speed with which it arrived from amazon. Amazon always treats us great! Thank you!

Bon outil pour une personne qui ne veut pas faire de calcul exemple vol x amp = watt Transformer watt en btu et diviser par (1.08xdelta t)= cfm ouf
