JUMO Conductivity Sensors – Reliable Control in Water and Process Applications
JUMO conductivity sensors are essential when precise monitoring of dissolved ions is required – whether in water treatment, industrial processes, or environmental analysis. At HeylNeomeris, we offer selected models that deliver consistent performance under demanding conditions.
Why JUMO sensors are the right choice:
• They ensure accurate conductivity readings across a wide measuring range
• With durable materials and IP65/IP67 protection, they withstand harsh environments
• Digital outputs and temperature compensation enable seamless process integration
• Two- and four-electrode versions cover diverse application needs
Electrical conductivity is a measure of how well an aqueous solution can conduct an electric current. It directly depends on the concentration of dissolved ions (salts, acids, or bases) in the water. The more charged particles are present, the higher the conductivity.
Conductivity measurement is a simple, fast, and reliable indicator of water quality. It is often used to monitor ultrapure water, process water, and wastewater. However, conductivity is a non-selective parameter—it does not indicate which substances are dissolved, only their total amount.
JUMO conductivity sensors are used in a wide range of applications, such as:
- Drinking and ultrapure water treatment: Monitoring purity levels and detecting contamination early.
- Chemical and pharmaceutical industry: Process media control and verification of product quality.
- Food and beverage industry: Monitoring of CIP cleaning cycles and product water quality.
- Wastewater treatment: Inlet and outlet monitoring for regulatory compliance.
- Power plants: Monitoring feed water to prevent corrosion and scaling.
Other areas of application include:
- Boiler feed water and condensate monitoring
- Reverse osmosis and ion exchange systems
- Environmental monitoring (e.g., rivers and lakes)
- Aquaculture and fish farming
- Battery water and cooling circuits

2-electrode principleproven versions for industrial use measuring ranges 0 ... 1 mS/cm (K = 0.1) or 0.01 ... 15 mS/cm (K = 1.0) temperature range up to 55 °C, maximum pressure up to 6 bar at 25 °C JUMO ecoLine CR-PVC conductive 2-electrode conductivity sensorBrief description: Conductivity sensors of the 202923 series are used, for example, in general water technology, cooling and air-conditioning systems, drinking and bathing water, or in industrial rinsing and process water circuits. The body material PVC limits the application to medium temperatures up to 55 °C. Two versions with cell constants K = 0.1 or 1.0 are available. Versions with the common thread sizes G 3/4" or G 1" or a plug-in version are available for installation. The plug-in version is used, for example, with the matching PVC tees in nominal sizes DN 25, 32 and 40 and allows the sensor to be quickly dismantled for cleaning or maintenance. The electrical connection is made either via a detachable device plug or via a fixed cable connection. The overall construction and the parts in contact with the medium are physiologically harmless. The electrode material is stainless steel (K = 0.1) or special graphite (K = 1.0). The optionally integrable temperature sensor allows simultaneous recording of the medium temperature for temperature compensation in downstream measuring amplifiers.Stainless steel variant K = 0.1 The sensor has 3 metallic pin electrodes. The two outer pins are electrically connected and form one pole of the 2-electrode conductivity sensor. The counter electrode is the middle stainless steel pin. This design achieves very high measurement precision with low stray fields. A temperature sensor can be integrated in the middle pin. Graphite variant K = 1.0 For physical reasons, special graphite is used as the electrode material for higher conductance values. The two graphite electrodes are completely integrated in the electrode shaft. The optional temperature sensor is located in a stainless steel sleeve that is immersed in the measured medium. Operating principleThe sensors of the 202923 series are 2-electrode conductivity sensors. An AC voltage is applied to them by the transmitter. The current flowing across the liquid and the electrodes is determined by the conductivity of the liquid
