Flow-Through

ARF 200 / ARF 202
SS Flow-through Fitting for One Sensor

A compact flow-through fitting for one pH/ORP, conductivity, or oxygen sensor in a sample loop with a 90° direction of flow.

316 SS stainless steel
Suitable for high pressures and temperatures

Description

The ARF 200 / 202 is a compact 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 316 SS stainless steel and is suitable for high pressures and temperatures. The ARF 200 utilizes olive compression fittings for process connections. The ARF 202 can have either a G 1/4″ female thread or ¼” NPT female thread as the process connections. As a standard, the ARF 200 and 202 accept conductivity sensors with a 1″ connection size (either G 1″ or 1″ NPT). In addition, adapters are available for receiving 12-mm sensors with PG 13.5 connections and 12-mm sensors with electrolyte reservoirs (ex: SE 557).

Applications for the ARF 200 / ARF 202 Flow Through Fitting

pH, ORP, conductivity, and oxygen measurement in ultrapure water
Steam Water Analysis System (SWAS) retrofits
Slightly polluted water
Cooling water
Drinking water
Trace-oxygen measurement in boiler feedwater
