Description

SE555 pH Sensor | VP | 325 mm | Ex | Sterilizable | For aggressive media

Sterilizable pH sensor providing high reliability and precision.

  • Gel electrolyte, pressurized
  • Ceramic junction
  • Silver ion trap
  • Integrated temperature detector
  • pH glass with high impedance for high-temperature applications, low alkali error
  • CIP/SIP-capable, safe sterilization with temperature monitoring

The SE555X/*-NVPN pH sensor comes with a special pH glass with high impedance for high-temperature applications  and a low alkali error. The sensor is CIP and SIP-capable. The silver ion trap prevents silver sulfide precipitation and junction fouling in media containing sulfides. This makes the sensor ideal for routine applications in food processing and biotechnology.

Applications
Fermentation, food and beverages, aggressive media, extreme pH values

We look forward to hearing from you!

Used in Process or Applications

Cooling water systems
Cooling towers are used in a range of industrial sectors for diverting process heat from cooling circuits. Mineral deposits and corrosion reduce efficiency and lead to the premature wear of system components.
Brewery processes
The taste and quality of beer greatly depend on the quality of the water used to brew it. pH and conductivity measurements determine its quality. Globalization is putting massive competitive pressure…
Monitoring sugar production
pH sensors are subject to extreme requirements during sugar production. Lime is dosed based on pH measurement right from the start...
