Dwyer Instruments 475-0-FM-AV | Air velocity kit | Range 0-10.00" w.c. (2.491 kPa) | Max. Pressure 5 psig | Kit includes static pressure tips | Rubber tubing | Pitot tube | Step drill | Air velocity slide chart and carrying case
The lightweight, user-friendly Dwyer 475-AV air velocity kits are a simple all-in-one solution. There is no need for leveling or setup. Its huge 1/2" LCD readout features a "low battery" warning and is easy to view in dimly light environments. A 6" stainless steel Pitot tube with an integrated compression fitting is included, ensuring that it is held firmly in place while taking readings. Two static pressure tips with magnetic mounting are also included for measuring pressure drop across filters, condenser coils, and other components. Rubber tubing, a 9V battery, a step drill, an AV calculator slide rule, and a specially made carrying box are all included in the set. Air velocity kit, maximum velocity, range 0–10.00" w.c. (2.491 kPa).
