SG pH probes for improved grounding, diagnostics and redox measurement

The InPro 4800 family with substantially prolonged operational life in the presence of aggressive chemicals or at high operational pressures, significantly reduces electrode maintenance and replacement costs in industry. The probe offers reliable measurements in oxidising media, strong acid or alkali solutions, sulfide-bearing media etc.

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.
