Digital pH sensor
Orbisint CPS11D

Memosens glass electrode for standard applications

Orbisint CPS11D is the digital all-rounder for process and environmental technology. It measures reliably even in highly alkaline media or hazardous areas. Designed for low maintenance and a long operating life, the electrode offers you best value for money. Thanks to Memosens digital technology, CPS11D combines maximum process and data integrity with simple operation. It resists corrosion and moisture, enables lab calibration and facilitates predictive maintenance.


·         Robust electrode with long poison diffusion path, requires low maintenance due to large, dirt-repellent PTFE ring diaphragm

·         Suitable for harsh applications: Process glass for highly alkaline media and pressure-stable up to 16 bar (232 psi)

·         Optional salt ring for low conductivity applications such as boiler feed water and water for injection

·         Maximum process safety through non-contact, inductive signal transmission

·         Enables predictive maintenance due to storage of sensor and process-specific data

·         Reduced operating costs thanks to minimized process downtime and extended sensor lifetime

Field of application

·         Long-term monitoring and limit monitoring of processes with stable process conditions:
- Chemical industry
- Paper industry
- Power plants (e.g. flue gas washers, boiler feed water)
- Incineration plants

·         Water treatment:
- Drinking water
- Cooling water
- Well water

With ATEX, FM, CSA approval for use in hazardous areas.
