The ILM-4 Is Ready When You Are

The Anderson-Negele ILM-4 Conductivity Meter is available for quick delivery in our most popular configuration (ILM-4L50TC2HI42MLWX) in as little as 1 day*, depending on shipping location and quantity.

With a proven 5-year reliability track record and modern IO-Link + analog connectivity, the ILM-4 is built to drop into your process and outperform legacy conductivity probes. Upgrade to the Anderson-Negele ILM-4 Conductivity Meter and eliminate probe failures for good.

Built for Food and Beverage Processes

The ILM-4 is designed for the demands of food and beverage applications, giving you precise inline conductivity measurement during both production and CIP/SIP cycles. Its 1.2-second response time means phase transitions are detected fast, so you're draining or recovering cleaning media at exactly the right moment rather than on a fixed timer. That translates directly to less product loss, less water consumption, and better use of your cleaning chemicals.

The sensor head is made of 100% PEEK, eliminating the thermal stress cracking that can occur in high-temperature CIP/SIP environments. Compensated detection runs up to 266°F (130°C), with CIP/SIP cleaning tolerance up to 302°F (150°C) for 60 minutes.

Flexible Connectivity, Ready for Modern Processes

The ILM-4's Flex-Hybrid Technology delivers IO-Link and 4...20 mA analog output in parallel, fitting into whatever your control architecture looks like today, while keeping the door open for smarter, more connected processes down the road. Bidirectional IO-Link communication means you can monitor sensor status and stay ahead of maintenance without waiting for something to go wrong.

A Sensor Built to Last

The ILM-4 is backed by an industry-leading 5-year warranty and delivers reproducibility within 1% of measured value. Its modular design is configurable from a straightforward base model up to a full-featured setup, and the remote version's Smart Replace Design makes component replacement plug-and-play, with automatic detection and parameterization.
