The GA-YQ2 Liquid Isolator is designed to reduce the influence of liquid media during pressure instrument calibration and maintenance. It is widely used for oxygen gauges, acetylene gauges, and other sensitive pressure devices where clean and stable pressure transmission is required.

Instead of using a diaphragm-type dual-chamber structure, the GA-YQ2 adopts a specially designed flow channel that separates liquid droplets and contaminants from the pressure medium through directional flow change and gravity settling. Similar to a cyclone-style separation principle, the internal structure helps collect liquid residues inside the chamber, reducing the risk of contamination entering calibration equipment and test instruments.
