Kit contents and intended use

The A-472 accessory kit supplies the probes, tubing, drill bit and reference chart needed to operate compatible Dwyer digital manometers. It is designed for technicians who measure static pressure in HVAC and air-flow applications.

Compatibility check before ordering

Verify that the manometer in use is a 475-1-FM, 475-2-FM, 475-3-FM, 477-1-FM, 477-2-FM or 477-3-FM model, as the kit is built specifically for that series. The package is not intended for other brands or for standalone pressure testing without a supported meter.

How it fits into a measurement setup

Magnetic static-pressure tips and rubber tubing connect directly to the instrument, while the step drill prepares mounting holes in ductwork. The included polyethylene case keeps all components organised and protects the pitot tube during transport and storage.
