SC24 differential pH sensor

The SC24 differential pH sensor is unique to the industry. Offering the possibility of maintenance free operation without any reference problems. In the SC24 differential pH sensor, the reference cell is made of glass, with no porous junction. No electrolyte is in contact with the process.

The differential measuring principle combines the normal potential generated by the pH glass with the potential from a Sodium pNa glass. In applications where Sodium-, Potasium- or Calcium-salt is present the glass will generate a stable reference voltage.
This means the measurement can be done without a conventional reference electrode, eliminating problems caused by aging and pollution of the liquid junction.

Features
• Sterilizable pH sensor
• No reference electrode or junction
• Low maintenance
• No diffusion = high stability


Applications
• Process where KCL is forbidden
• Process with rapid temperature / pressure changes
• Chlorine manufacturing (electrolysis of Brine)
• Bio- ethanol fermentation processes
• Pulp and Paper
