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.

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.
