The Dwyer A-302 Static Pressure Tip is designed for accurate static pressure measurements in various applications, including monitoring the pressure drop across industrial air filters and refrigerant coils.  It is especially effective in scenarios where air turbulence might affect measurement accuracy, as its design helps to minimize impingement and aspiration by positioning the sensing openings away from duct walls.

This static pressure tip features a permanent installation option with a 4˝ insertion depth and is equipped with four radially drilled .040˝ sensing holes to ensure precise readings.  Capable of handling airflow velocities up to 12,000 FPM, the A-302 is mounted securely in a 3/8˝ hole within the duct.  It is compatible with 3/16" and 1/8" I.D. plastic or rubber tubing, making it versatile for various ductwork and measurement setups.
