The ARF 201 is a compact plastic flow-through fitting for one pH/ORP, conductivity, or oxygen sensor in a sample loop with a 90° direction of flow. The fitting is made of PP and is suitable for low pressures and temperatures. The fitting can have either a G 1/4″ female thread or ¼” NPT female thread as the process connections. As a standard, the ARF 201 accepts conductivity sensors with a 1″ connection size (either G 1″ or 1″ NPT). In addition, an adapter is available for receiving any 12-mm sensors with PG 13.5 connections.

Applications for the ARF 201 Flow Through Fitting

• pH, ORP, conductivity, and oxygen measurements
• Slightly polluted water
• Cooling water
• Drinking water
• Corrosive processes
