Featuring a slim 38-inch telescoping probe with laser-etched markings, it enables precise positioning and automatic CFM calculation. Its dual display provides real-time data for efficient air balancing, making it an essential compact instrument for HVAC technicians. ## Description Product description Measure Airflow Directly In-Duct 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.
