Features and Benefits
Cut maintenance and replacements costs
  • This is due to a unique technical design, with a very long diffusion path in a double electrolyte chamber with a dirt-repellent annular junction (PTFE).
 
ISM ("Intelligent Sensor Management®")
  • METTLER TOLEDO’s new and innovative, digital “Intelligent Sensor Management®” concept provides “Plug and Measure” functionality. ISM simplifies and improves the operation of process analytical systems from initial installation to maintenance to sensor exchange. ISM technology provides you with advanced diagnostic functions, lower maintenance costs and reduces the risk of sensor failure, while also improving process reliability. More information about ISM
 
Allows highest operational pressure over a wide temperature range
  • The very high pressure specification is valid in the whole temperature range, see specification.
 
Compliance with safety regulations for Ex-classified zones
  • The electrode is Ex-certified and can be used for processes in Ex-classified zones.
 
Flat membrane for abrasive media increases process safety
  • The InPro4801SG with a flat glass membrane and solution ground is the optimal choice for media with particles and fibers. Ground loops can be avoided with the solution ground, which can also be used as a diagnostic tool.
 
Solution ground (SG) as an option
  • The SG feature as an entire electrode body coating or as a measuring point on a pH-electrode, will improve grounding and effectively eliminate the risk of electrostatic interference. SG also improves our advanced diagnostic functions, and makes parallel pH/redox measurement possible.
 
New rugged construction with titanium shaft
  • The new 4881i electrode provides exceptional chemical and mechanical resistance thanks to the titanium shaft and stainless steel thread.
