Features of the N-FLASH50 Device The N-FLASH50 is a compact, battery-powered conductivity meter designed to monitor conductivities in the range of 0 to 50 µS/cm. Thanks to its handy design, it is ideal for mobile use and short-term measurements directly on site. The clear LED display allows quick evaluation of measurement results without additional analysis devices. Mobile Conductivity Meter for Quick Checks Three integrated LEDs clearly indicate the current measurement status: green signals a safe range, yellow indicates threshold levels, and red warns of excessively high conductivity. The integrated 3/4"-threaded measurement cell allows direct installation in pipelines and ensures uncomplicated measurement during ongoing operations. Battery operation provides maximum flexibility, independent of external power supply. Why Conductivity Is Measured in Water Treatment Conductivity indicates how many dissolved salts and ions are present in water. It is therefore an important indicator for assessing water quality. In water treatment, it is used to monitor desalination and treatment processes and to detect deviations from target values early. Excessively high conductivity values can indicate exhausted filters, defective membranes, or contamination. Regular measurement protects equipment, ensures process quality, and helps comply with regulatory limits.

Features of the N-LF10R Conductivity Meter Compact meter for monitoring low conductivities in the 0–10 µS/cm range The N-LF10R measures the conductivity of water in the extremely low range of 0–10 µS/cm and is suitable for high-purity applications. The potential-free relay output allows the activation of switching devices when limit values are exceeded. The integrated two-electrode 3/4" screw-in measuring cell operates without temperature compensation. Technical Specifications Measurement ranges: 0–10 / 100 / 1000 μS/cm, depending on device type Limit value display: visual via LEDs, limits adjustable between 0 and 100% of the measurement range 1 potential-free relay contact, max. 2 A / 250 V AC, 60 W / 62.5 VA (optional) Power supply: 9 V DC via plug-in power supply 100–240 V AC Power consumption: approx. 1 W Protection class: IP65 Housing: polycarbonate, 82 x 60 x 57 mm Connections: side connection for power supply and 1x relay output (optional) Measuring cell: 3/4", PP, PN 6, Tmax 60 °C Precise Monitoring of Extremely Low Conductivities up to 10 µS/cm The N-LF10R conductivity meter was specifically designed to measure very low electrical conductivities in the 0–10 µS/cm range. It is ideal for high-purity applications where even the smallest changes in conductivity must be reliably detected. The integrated two-electrode 3/4" screw-in measuring cell enables direct inline measurement without additional sensor equipment. By omitting temperature compensation, the device delivers stable and clearly reproducible readings, especially in processes with constant temperatures. Benefits of the N-LF10R for Process Monitoring and System Safety A key advantage of the N-LF10R is the potential-free relay output, which allows external switching devices or alarm systems to be triggered when limit values are exceeded. The optical LED limit display also allows quick visual monitoring of the current measurement status. Thanks to the compact IP65 housing, the device is protected against dust and splash water and is suitable for installation in control cabinets as well as for field use. The energy-efficient operation via a 9 V DC plug-in power supply makes the N-LF10R a reliable and low-maintenance solution for continuous monitoring of very low conductivities.
