pH Sensor DGi112-Pro
Adaptable titration for tough matrices.The DGi112-Pro is a double-junction pH sensor designed for specific adaptation to difficult sample matrices. Ideal for titration of acid mixtures in demanding electrochemical baths.
Specifically Adaptable
A special double-junction design enables replacement of both the reference and bridge electrolytes, for optimization to your specific matrix.
Durable Membrane
The HA glass membrane features both tough durability and rapid response, while the movable diaphragm prevents clogging and enables easy cleaning.
Make Difficult Titration Easy
Enables direct pH and acid-base titration in difficult aqueous (plating baths, sulfide-containing samples) and non-aqueous matrices.
Material No.: 51109501
Features
Plug & Play Sensor Chip
A sensor chip stores the sensor type, calibration, and lifespan data, all read instantly during titrator setup. Using the wrong sensor is impossible.
Precision and Reliability
The combination of experienced craftsmanship plus maximum utility of automated production methods ensures consistently high sensor performance.
Guaranteed Quality
No sensor leaves the production facility untested. Only after a series of demanding final checks does each sensor receive its individual quality certificate, ready for dispatch.
