pH Sensor InPro4281i/SG/425
Rugged, Long-Lasting pH Probe.The InPro 4281i is a pH probe with a titanium shaft for exceptional durability in demanding chemical applications. It provides ISM advanced diagnostics to optimize maintenance decisions and sensor lifetime.
Withstands Demanding Applications
The InPro 4281i uses a polymer reference system and a titanium shaft for reliable pH measurement, even under difficult industrial conditions.
Advanced Predictive Diagnostics
This pH sensor has Intelligent Sensor Management (ISM) technology, offering predictive diagnostics to reduce maintenance and simplify calibration.
Accurate pH Measurement
The InPro 4281i provides a wide measurement range from 1-14 pH and has a solution ground for enhanced stability.
Material No.: 30301404
Features
Eliminates Clogging & Resists Poisons
The InPro 4281i features an open junction Argenthal reference system with a Xerolyt® Extra polymer electrolyte that eliminates sensor clogging and ensures the sensor is resistant to poisoning, solvents, and strongly acidic or basic conditions.
Optimizes Maintenance Cycles
This pH sensor features intelligent diagnostics to help manage your maintenance. The sensor provides a clear display of its remaining lifetime, time remaining until calibration is needed and indicates when the sensor will need to be cleaned.
Suitable for Hazardous Conditions
The InPro 4281i is ATEX and FM certified for hazardous areas. It can withstand temperatures up to 176°F (80°C) and has a titanium shaft to resist the daily knocks of industrial manufacturing.
Fast Replacement of Sensors
Ensure the safety of the maintenance team with the ability to Plug & Measure. The InPro 4281i can be calibrated away from the process and then quickly swapped into the process environment without the need to recalibrate.
