Detailed Description
The CS526 uses SENTRON’s high-tech, ion sensitive field effect transistor (ISFET) semiconductor 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. The 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.
Note: Campbell Scientific warranty does not cover a clogged reference diaphragm or improperly cleaned or maintained ISFET chip. (See the Maintenance section in the instruction manual for more information.)
This sensor requires the 5 V output on the data logger to be powered..

-
The CR300 and CR310 dataloggers do not support TTL logic, which is what the CS526-L sensor uses. A TTL to RS-232 converter (supplied by the user) could be used, however.
