Our Neomeris conductivity cell with 12mm connection is used for the determination of the electrical conductivity in aqueous solutions.  Inside the T-piece is the two-electrode measuring cell without temperature compensation. The installation is easy and fast due to the John Guest connectors. We recommend the use of the product in the fields of distillate, condensate, ultrapure water as well as fully demineralized water. Technical data Material Housing: POM T-piece John Guest ½" Material electrodes: V4A 4571 Cell constant: C = 0.1 +-5% Max. operating pressure: 6 bar Max. operating temperature: 60°C Electrical connection: - brown electrode, outer sheath - white Electrode, inside - blue: shieldCable length: 2.5 meters

Connection cable for pH/redox Length: 3 metres Cable type: pH and redox connection cable Ø 5 mm, 75 °C Connection end 1 (sensor side): rotatable cable socket Connection end 2 (device side): without Electronic sensors for analysing liquids require special connection cables and plug connectors. The following applies in principle: The connection between an electrochemical sensor and the transmitter/indicator/controller should be as short as possible. Normally, the cable length is 5 to 10 metres to ensure a high level of functional reliability. If longer cable lengths are required in exceptional cases, the technical documentation for the sensors and measuring devices should be consulted. The cable between the sensor and the analyser must be laid directly, without interruptions such as terminal strips or cable extensions. pH and redox measurement Special coaxial cables with a special design are used for pH and redox measurement. During these measurements, the sensor generates low-intensity DC voltages which are transmitted to the analyser. Due to the sometimes very high internal resistance (potentiostatic measuring principle with internal resistances of up to several gigaohms), these measurements are extremely sensitive to electrical interference and the effects of radiation. Under unfavourable conditions, even minimal movements of the cable can lead to measurement value distortions. An additional insulation layer of the JUMO coaxial cable increases the insulation resistance, which enables a secure connection of the sensor to the transmitter. Conventional coaxial cables from the antenna and computer sector are not suitable for this application and can damage the sensors. This can lead to immediate failure of the sensor as well as a shortened service life. For multiple sensors, for example with integrated temperature sensors, coaxial cables with single wires are available, such as the Variopin (VP).

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.
