Capacity measurement ion exchanger cartridgeOur Neomeris N-FLASH10 conductivity meter in a T-piece with 3/8 inch connection is a conductivity measuring instrument that is used to monitor the electrical conductivity of water after flowing through the ion exchanger cartridge. The measuring instrument including the integrated measuring cell is battery operated and permanently installed in the T-piece. If the measured electrical conductivity is below the limit value of 10µS/cm, the green LED flashes; if it is above, the red LED flashes, indicating that a cartridge or resin change is required. Due to the T-piece used, the measuring device can also be integrated very easily and is optimally installed in the liquid flow for a stable measurement. Measuring principle: The measuring cell generates an electrical signal that is proportional to the conductivity of the liquid. This signal is processed in the device and the LED is controlled via the programming stored in the device. Application: Conductivity meters are often used in water treatment plants in the process industry.Technical data:Screw-in thread: 3/8"; others available upon requestMaterial housing: POM black Material lid: Plexiglas Material electrodes: V4A 4571 Material O-ring: EPDM Cell constant: C= 0.6 +/- 10% Max.

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. Frequently asked questions Are there other measuring ranges available?
