User Manual

8. If LoggerNet, PC400, or PC200W is running on your PC, and the PC to

datalogger connection is active, you can click Finish in Short Cut and you

will be prompted to send the program just created to the datalogger.

9. If the sensor is connected to the datalogger, as shown in the wiring diagram in

step 6, check the output of the sensor in the datalogger support software data

display to make sure it is making reasonable measurements.

5. Overview

The CS526 uses SENTRON’s high-tech, Ion Sensitive Field Effect Transistor

(ISFET) semi-conductor as its pH-sensitive element, and includes a silver/silver

chloride – potassium chloride reference system.

The CS526’s design allows it to be suitable for a variety of liquid pH-monitoring

applications. Its electronics are safely embedded in a durable PEEK body.

Elimination of the glass-bulb removes the possibility of broken glass, making the

CS526 more rugged and safer to use.

The CS526 is shipped dry and therefore must be soaked in pH

solution before use.

6. Specifications

Features:

• Safety — the ISFET with durable PEEK material can be used safely in

applications where broken glass is a hazard to the user.

• Intelligent electronics — the CS526 combines the latest developments in

ISFET pH sensing technology with state-of-the-art signal processing.

This allows for accurate, fast and reliable results.

• Quality — designed and manufactured under stringent quality control

conditions in an ISO 9001 environment. Each sensor is individually

tested to the most demanding testing protocols, and the electronics

comply fully with directives and with EMC standard IEC61326:2005.

• Compatible with Campbell Scientific CRBasic dataloggers: CR800

series, CR1000, and CR3000.
