Featuring a 38" telescoping probe with laser markings, dual real-time displays, and hands-free magnetic mounting, it enables precise air balancing and system diagnostics without bulky capture hoods. ## Description The STA2’s slim hot wire probe is designed to be inserted directly into ductwork, allowing you to capture real-time air velocity and temperature exactly where it matters. By measuring airflow inside the system—rather than at vents or grilles—you can calculate more accurate CFM, reduce guesswork, and make confident adjustments during air balancing and diagnostics. It’s a faster, more precise way to verify system performance without the need for bulky capture hoods.

Also a “tip protector”. Nice meter. **Q: What is the diameter at the top of the probe?** A: Please note that the manufacturer confirmed that it is slightly bigger than 3/8''. **Q: Will this measure cfm at the supply plenum of an air handler?** A: Yes. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product, *by on Reviewed in the United States October 25, 2024* After learning how to properly use the tool, I was able to offer better results for my service calls. ### ⭐⭐⭐⭐⭐ Accurate and handy for *by on Reviewed in the United States May 25, 2026* 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 ### ⭐⭐⭐⭐⭐ Very High Tech Instrument *by on Reviewed in the United States August 18, 2019* 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. ## Frequently Bought Together - Fieldpiece STA2 in Duct Hot Wire Anemometer - Fieldpiece - Job Link System Dual Port Manometer Probe Kit - JL3KM2 - Long Range Wireless All-in-One Static, Gas and Draft Pressure Gauge - HVAC Tools - Fieldpiece JL3RH Job Link Flex Psychrometer Probe w/Remote Data Logging for BLE 4.0 Devices, 2.4 GHz Radio Frequency, 0% RH to 100% RH Measurement Range --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/4910495-fieldpiece-sta2-in-duct-hot-wire-anemometer-for-hvac-airflow](https://www.desertcart.jp/products/4910495-fieldpiece-sta2-in-duct-hot-wire-anemometer-for-hvac-airflow) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-17*
