CS526 ISFET pH Probe

1. Introduction

The CS526 ISFET pH Probe measures pH from 1 to 14 in aqueous or semi-

solid solutions. It outputs TTL serial data that is read by compatible

dataloggers (see Section 6, Specifications

(p. 5)).

Before using the CS526, please study

• Section 2, Cautionary Statements

(p. 1)

• Section 3, Initial Inspection

(p. 2)

• Section 4, Quickstart

(p. 2)

More detailed instructions for operation, troubleshooting, and maintenance are

available in the remaining sections.

2. Cautionary Statements

• READ AND UNDERSTAND the Precautions section at the front of this

manual.

• Campbell Scientific warranty does not cover a clogged reference

diaphragm or improperly cleaned or maintained ISFET chip (see Section

9, Maintenance

(p. 10)).

• Maximum input voltage is 5 Vdc. Incorrect wiring may cause

performance loss and irreversible damage.

• To prevent scratching the sensor chip when cleaning, first soak the sensor

in soapy water and then gently scrub with a toothbrush (see Section 9,

Maintenance

(p. 10)). Most scratches occur when hard particles are rubbed

on the chip surface. Scratches cause irreversible damage to the probe.

• Do not use hydrofluoric acid, acetone, MEK, or similar agents to clean the

probe.

• Cable can be damaged by abrasion, rodents, sharp objects, twisting,

crimping or crushing, and pulling. Take care during installation and use to

avoid cable damage.

• The CS526 is rugged, but it should be handled as a precision scientific

instrument.

• The CS526 has no user-serviceable parts. Any attempt to disassemble the

device will void the six-month warranty.

• Care should be taken when opening the shipping package to not damage or

cut the cable jacket. If damage to the cable is suspected, consult with a

Campbell Scientific application engineer.
