Dwyer Instruments A-350 | Aspirator Bulb | Used as pressure source in calibration and leakage tests

Part Number : A-350

Testing for leaks and calibration can be done using the Model A-350 Aspirator Bulb as a source of pressure. To create pressure, just squeeze the bulb once the tube is connected. Squeezing the aspirator bulb before entering the tubing creates a vacuum that draws smoke or air from a duct or stack into the gage, which is useful for applications like our CO2 indicator.
