Dwyer Instruments A-302 Pressure Tip R-134A the motor may struggle toThe Dwyer Instruments A 302 Pressure Tip is an angled sensing component engineered for precise static pressure measurement in high velocity HVACR environments. Designed with a 4 inch insertion depth, this static pressure tip effectively bypasses the turbulence and aspiration effects common near duct walls, ensuring your manometers and Magnehelic gauges receive a clean signal. The probe features four radially drilled . 040 inch sensing holes that allow
