pH Sensor PHEP 112 SE

Your benefits

•  Electrochemical combination electrode: pH and reference electrode integrated
•  Diaphragm and reference system optimised for exacting process requirements
•  Ceramic diaphragm with special material, optimised size and optimised pore diameter
•  Long service life due to reduced diffusion (“bleeding”) of the electrolyte
•  Long service life due to the material, which is inert to aggressive disinfectants
•  Stable reference system for high pressure/temperature requirements
•  Twist protection for the sensor cable connected. This means that the cables can remain connected
• during installation and dismantling of the sensor, avoiding troublesome moisture on the connector
• contacts
•  Lead-free glass for advanced and environmentally-friendly production, use and disposal (RoHS-
• compliant)
