pH Sensor DGi117-Water
For all Water Titration Needs.Combined pH sensor with ground glass sleeve junction. For direct pH measurement and acid-base titration, with simultaneous temperature measurement in aqueous solutions of low ion conductivity and low buffer capacity.
No Watering Down of Sensor Data
All pH sensor calibration data is stored on a sensor chip and automatically and instantly transferred to the titrator as soon as it is connected.
Maintenance Free Reference
Double-junction design with maintenance-free internal reference system enables reference electrolyte replacement and adaptation to test conditions.
No Interference
A gold-coated, electrically shielded inner tube prevents interference from electrostatic charges, reducing signal noise and pH reading drift.
Material No.: 51109506
Features
High Precision in Low-Ion Media
Electrolyte flow through the fixed glass junction remains stable between 5 and 20 μL/h, guaranteeing accurate pH readings and minimal sample contamination by electrolytes.
Temperature All-Inclusive
Temperature-adjusted pH readings and end point titration can be performed thanks to the integrated Pt1000 temperature sensor.
Rapid Results
LoT glass brings low membrane resistance and ensures extremely fast response time. Thin-walled spherical design reduces electrical resistance even further.
