CS526 ISFET pH Probe
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.
The CS526’s cable can terminate in:
• Pigtails that connect directly to a Campbell Scientific datalogger
(cable termination option –PT).
• Connector that attaches to a prewired enclosure (cable termination
option –PW).
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
Measurement
Range: 2 to 12 pH
