1. PREFACE 1.1 Introduction This instruction manual provides information for the installation and use of the FU24 four-in-one wide body pH sensor, which is especially designed for harsh process applications. The Model FU24 offers a simple and cost effective solution for process applications with fluctuating pressure and/or temperature which normally limit the lifetime of a sensor. By using the patented Bellow system a strong pressure compensation mechanism is created.
1.3 Warranty and Service Yokogawa products and parts are guaranteed free from defects in workmanship and material under normal use and service for a period of (typically) 12 months from the date of shipment from the manufacturer. Individual sales organizations can deviate from the typical warranty period, and the conditions of sale relating to the original purchase order should be consulted.

3. INSTALLATION OF FU24 For optimum measurement results, the FU24 should be installed in a location that offers an acceptable representation of the process composition and DOES NOT exceed the specifications of the sensor. The FU24 is designed with 1” NPT threaded connections on both ends of the sensor to allow installation in a wide variety of applications. 3.1 Typical installation The FU24 sensor is designed for versatile in-line, immersion or off-line installation.

6.2 Calibration for ORP and rH measurement For calibration of ORP and rH, the procedure for MANUAL CALIBRATION can be used as described in the Instruction Manual of the analyzer. The rH value is a function of the reference system and the pH value of the buffer solution. The FU24 sensor has a reference system of saturated Silver/Silver Chloride (Ag/AgCl). The commonly used standards for ORP and rH calibration are made from Chinhydron (Quinhydrone) powder dissolved in pH buffer solutions (1 g / 200 ml).
