Performance in Harsh Conditions
This pH sensor is designed to perform accurately in demanding industrial environments, at low and 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.
Material No.: 30301407
The InPro 4881i eliminates the replacement costs of accidentally broken glass pH sensors. The titanium shaft protects the pH glass, so a dropped sensor will not shatter and a bumped sensor will not break.
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.
The InPro 4881i is ATEX and FM certified for hazardous areas.
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.
This pH sensor has a solution ground that improves grounding and effectively eliminates the risk of electrostatic interference.

The DS AK9-RJ12 is a USB cable adaptor for connecting ISM 1-wire sensors to iSense software. This allows pH, DO and CO2 sensors to be evaluated, maintained and calibrated in the workshop or laboratory.
Diagnostics Away From the Transmitter
The iLink module allows you to access all of the diagnostics of your ISM sensors away from the process with iSense desktop software.
Application Profiling Drives Performance
Store application data on iSense and load directly into an ISM sensor. This allows sensors to learn from preceding sensors in the same process.
Easy Access to Paper Free Documentation
The iLink cable allows sensor calibration and adjustment protocols to be generated automatically in iSense and stored in a fully digital database.
