1 Introduction

1.1 Purpose

This instruction manual describes the installation and maintenance of the AP300 Series Industrial pH and Redox (ORP) Electrode
Systems.

1.2 Sensors and Systems

There are three main sensor types:
— AP301 Standard twist-lock – insertion, flow-through, immersion
— AP302 Screw in – insertion, immersion
— AP304/5 Ball valve insertion, hot-tap

1.3 Sensor Descriptions

1.3.1 AP301

Model AP301 sensors are twist-lock general purpose insertion, flow-through or immersion style. The sensor body is molded from
chemically resistant PPS (Ryton).
The sensor can be adapted to 1 inch fittings by a threaded Ryton twist-lock adaptor.
An optional PVC electrode guard protects the electrode in immersion applications.
