Reliable Monitoring of Water Quality at Extremely Low Conductivity High-precision conductivity meter for ultrapure and process water The N-LF5R meter was developed for continuous monitoring of very low electrical conductivities in aqueous solutions. With a measuring range of 0–5 µS/cm, it delivers meaningful readings even with minimal conductivity changes. The integrated 3/4" screw-in measuring cell allows direct installation into the process flow. Its compact design and low power requirement via 9 V DC operation make the N-LF5R highly flexible. The robust IP65 housing protects the device against dust and splash water, ensuring reliable operation even under demanding conditions. Why precise conductivity measurement is particularly important in the low range Even slight deviations in conductivity can determine the quality of the final product or the safety of a system in many processes. The N-LF5R detects the smallest changes in the 0–5 µS/cm range, which can indicate contamination, material degradation, or process deviations. Benefits of the N-LF5R for monitoring ultrapure and process water The N-LF5R conductivity meter enables early detection of even minimal changes in conductivity in ultrapure and process water. This allows contamination, leaks, material leaching, or process deviations to be identified quickly before they lead to quality issues or equipment damage. The integrated screw-in measuring cell allows direct inline measurement, ensuring continuous and reliable readings without sampling. Combined with the robust IP65 housing, the device is ideal for permanent use in industrial applications where high measurement accuracy and operational reliability are critical.
