Conductivity
Conductivity monitoring in water
The conductivity of water is a property that indicates the general quality of the water. Most of the substances dissolved in water are salts. The lower the measured value, the fewer dissolved substances (primarily salts) are dissolved in the water. Conversely, a high conductivity indicates a high salt concentration. Conductivity monitoring is of particular importance in the hospital sector. The DGSV (German Society for Sterile Supply) recommends certain limit values for the conductivity of process water to ensure that medical device reprocessing processes can be carried out effectively in hospitals.
High-quality conductivity meter for conductivity monitoring Our innovative conductivity meter has been specially developed for monitoring conductivity in ultrapure water (demineralised water) and has a 4-20 mA signal output that enables easy integration into higher-level control systems.The measurements are temperature-compensated, which ensures greater accuracy. With a measuring range of 0 to 2 µS/cm, our device is particularly suitable for monitoring low conductivities, such as those typically found in mixed-bed ion exchanger cartridges. The limit value is displayed by means of 2 LEDs (green/red) on the top of the device. An acrylic glass cover ensures that the current status is immediately visible. The device has a ¾ screw thread, which can be customised for easy and safe installation. There is also the option of customisation in terms of the LEDs, including the measuring range and a private label. Our high-quality conductivity meter offers a reliable solution for conductivity monitoring in medical areas to fulfil the guidelines and recommendations of the DGSV. Our measuring device is also particularly suitable for mixed bed cartridge monitoring in the clinical environment. Standard LED configuration (1 green LED, 1 red LED): <0.5 µS/cm = green >0.5 µS/cm to <1.0 µS/cm = green/red flashing >1 µS/cm = red
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.
