Name: pH Sensor InPro4800i/SG/425
Brand: Mettler Toledo

Performance in Harsh Conditions

This pH sensor is designed to perform accurately in demanding industrial environments, at high temperatures, and under high pressure.

Reduce Maintenance Costs

The PTFE annular junction, long diffusion path, and double electrolyte chamber combine to reduce cleaning and maintenance needs.

Advanced Predictive Diagnostics

This pH sensor has Intelligent Sensor Management (ISM) technology, offering predictive diagnostics to reduce maintenance and simplify calibration.

Top of the Line Performance

The InPro 4800i offers stable and precise measurement under extreme process conditions due to its highly alkaline resistant pH glass membrane, double chamber gel electrolyte reference system, and chemical resistance.

Made for Demanding Applications

This pH sensor has been designed to meet some of the most demanding pH measurement needs. It is optimal for processes containing sticky components, such as petrochemical production, pulp manufacturing, dye production, and sugar processing.

Suitable for Hazardous Conditions

The InPro 4800i is ATEX and FM certified for hazardous areas. It withstands temperatures up to 130°C (266°F) and has can handle operating pressures as high as 12 barg.

Optimizes Maintenance Cycles

This digital ISM pH sensor features intelligent diagnostics to help manage your maintenance. The sensor provides a clear display of its remaining lifetime and time remaining until calibration is needed.

Solution Ground Allows ORP Measurement

This pH Sensor has a solution ground that improves grounding and effectively eliminates the risk of electrostatic interference. It also makes parallel pH and redox (ORP) measurement possible with this sensor.
