Protected from Impact
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.
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 4881i is ATEX and FM certified for hazardous areas.
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 For Precise Measurement
This pH sensor has a solution ground that improves grounding and effectively eliminates the risk of electrostatic interference.

Accessories
Sensor Calibration & Maintenance Tools
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.
Material No.: 52300383
A universal device for connecting both 1-wire and RS485 ISM sensors to a computer running iSense software.
