Ultra-low pressure HVAC trunk line balancing and laboratory ventilation hood auditing reach absolute stability when using the Dwyer 477-000T-AV air velocity kit. This specialized instrument pairs an ultra-sensitive digital manometer tracking a narrow 0 to 1″ w.c. scope with a durable stainless steel pitot probe module layout. It functions smoothly down to a 0.001″ w.c. pressure resolution, recording subtle draft variations inside automated manufacturing plants.
