Fieldpiece ASP2 Magnetic Pitot Probes – Static Pressure Duct Measurement

The Fieldpiece ASP2 are a pair of 115mm magnetic pitot probes designed for fast, accurate static pressure measurement in HVAC ductwork. Their strong magnetic tips hold the probes firmly in place on sheet metal duct walls — freeing your hands to read the manometer and adjust the system without juggling tools.

Compatible with the Fieldpiece SDMN5, SDMN6, and ADMN2 manometers, the ASP2 probes are a practical addition to any HVAC technician’s commissioning and service kit. Browse the full Fieldpiece accessories range for compatible tools.

Key Features
