Vapor Quality Sensor

Category: HBX-DX - Angle rod

The Angle Rod version is suited for smaller systems and is made in stainless steel. It accepts flow in both directions and is suited for all common refrigerants. 

The sensor comes with reductions to compensate for a restricted flow area as standard. The sensor is made in stainless steel and can be butt welded (TIG) or brazed into the system. The sensor element can be removed and cleaned if necessary. The sensor is available from ¼” to 1” pipe size.
