The N-LF100 is a compact conductivity meter for monitoring the electrical conductivity of water in the range of 0–100 µS/cm. The integrated 3/4" screw-in measuring cell allows direct installation into a pipeline without a separate measuring cell. The device is ideal for applications where very low conductivities need to be monitored.

The N-LF100 measures the electrical conductivity of aqueous solutions in the 0–100 µS/cm range, making it suitable for very poorly conductive media. A clearly limited measurement range helps reliably monitor water quality within a defined low conductivity range. The integrated 3/4" screw-in measuring cell reduces installation effort.

Reliable Monitoring of Very Low Conductivities in the Process

The N-LF100 conductivity meter was specifically developed for monitoring very low electrical conductivities in the 0–100 µS/cm range. It is ideal for applications where water quality must be controlled in a clearly defined low conductivity range, such as in demineralized water, rinsing processes, or sensitive technical applications.

The integrated 3/4" screw-in measuring cell allows direct installation into pipelines, significantly reducing installation effort and enabling continuous inline measurement without additional sensors. The clearly defined measurement range ensures stable and easily interpretable readings.

Benefits of the N-LF100 in Daily Operation

The N-LF100 impresses with its simple operation and high operational reliability. The optical LED limit display allows quick visual monitoring of the measured value and immediately signals deviations. Optionally, a potential-free relay contact can be used to trigger alarms or automatically control processes.

Operation via a 9 V DC plug-in power supply ensures energy-efficient use while maintaining high flexibility. Thanks to the robust IP65 housing, the device is protected against dust and splash water and is suitable for installation in control cabinets or directly in the field. The N-LF100 provides a reliable solution for continuous monitoring of very poorly conductive media.
