Product description

Inductive conductivity meter ILM-4

With ILM-4 it is possible to directly measure the concentration of a medium which can effectively improve the CIP cleaning process and thereby also economically advantageous.


An effective CIP cleaning is dependent on a proper cleaning process. Too low concentrations can lead to insufficient cleaning results while too high concentrations result in increased product usage and longer flushing times, which in turn results in higher financial costs. The ILM sensor is perfect for controlling the right amount of detergent concentrations.

It is also suitable for product quality monitoring.


Other characteristics are:


- Now  available with

- Accurate measurement results due to temperature-compensated measurement

- High repetition accuracy, <1% of the measured value

- Fast response time, T90> 15 sec

- Analogue output (4-20 mA) for both conductivity and temperature

- FDA and 3-A approved

- Available in remote (shared) version, ILM-4R
