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..
Benefits and Features
- Innovative ISFET pH-sensing element
- Easily cleaned
- More rugged than the traditional glass electrode pH probes
- Each sensor individually tested
- Designed and manufactured under stringent quality control conditions in an ISO 9001 environment
- CE compliant
The CS526 isolated pH probe makes reliable, accurate pH measurements in aqueous solutions. It can be submersed or inserted into tanks, pipelines, and open channels. This probe has a serial, TTL output that represents a 2 to 12 pH range.
- CS526-L Digital ISFET pH Probe measures pH using state-of-the-art ISFET technology.
- There is no glass bulb to break, making the sensor safer and much more rugged.
- Provides better measurements in extreme pH conditions.
- The probe can go a longer time without servicing, is easier to clean, and can be stored dry.
- Electronics are safely embedded in a durable resin body
- Elimination of the glass-bulb makes the probe more durable and safer to use, allowing it to be deployed in the field for longer time periods
- Innovative ISFET pH-sensing element used that makes better measurements in extreme pH conditions
- Each sensor individually tested
