Water quality measurement

Water quality measurement devices are used to monitor the physical, chemical, and biological parameters of water. They enable reliable monitoring and evaluation of water quality in water management, industrial, and environmental applications.

Product type

Display, calibration and control units

Display, calibration, and control units are used to visualize, calibrate, and control measuring instruments. They enable reliable monitoring of measured values, precise sensor adjustment, and efficient management of technological processes.

Dual and multi-channel units

Two-channel and multi-channel units are used to display, analyze, and control data from multiple measurement channels simultaneously. They enable efficient monitoring, precise parameter adjustment, and reliable oversight of technological processes.

H3, H7 - Multichannel Recording and Control Units

H3, H7 - Multichannel Recording and Control Units

Versatile multi-channel data acquisition and control unit with GSM/GPRS (Wi-Fi) technology—Data Logger. The unit is suitable not only for monitoring and controlling water supply facilities (water reservoirs, pumping stations, transfer or metering shafts, water treatment plants, and wastewater treatment plants), but also for environmental monitoring. The unit offers high reliability, measurement accuracy, low power consumption, and automatic transmission of measured data to a server database.

E2 - Calibration and Control Unit for the Water Supply Industry

E2 - Calibration and Control Unit for the Water Supply Industry

The Process Controller E2 is a control unit and data logger designed for the numerical and graphical display and recording of data. It acquires this data from connected sensors for dissolved oxygen, pH, REDOX potential, turbidity, conductivity, ISE, and temperature. It also calibrates these sensors and controls connected equipment using internal relays and 4–20 mA current outputs.

Single-channel units

Single-channel units are used to display, analyze, and control data from a single measurement channel. They enable precise parameter settings and reliable monitoring of the measured process.

Electrochemical measurements

Electrochemical measurements are used to monitor chemical parameters of water, such as pH, conductivity, and ion concentration. They provide reliable data for assessing water quality in water management, industrial, and environmental applications.

Electrochemical probes series 485

The 485 Series electrochemical probes are used to measure chemical parameters of water, such as pH, conductivity, and ion concentration, with digital data transmission via the RS485 interface. They enable reliable data collection and integration into telemetry and control systems.

LCT 307i RS 485 Combined Sensor

LCT 307i RS 485 Combined Sensor

The LCT 307i combined sensor is designed for continuous measurement of water level, conductivity, and temperature in mineral water wells. A single sensor can thus be used to monitor the condition of mineral water in a well, pool, or borehole.

PH485 - Probes with RS485/Modbus RTU Output

PH485 - Probes with RS485/Modbus RTU Output

The PH485 probe features a combination pH electrode with partial self-cleaning capability and an extended service life. The self-cleaning design of the electrode ensures a stable and reproducible signal even in environments containing emulsions, suspensions, and other adhering contaminants of various origins, as well as contaminants caused by chemical reactions. The electrode thus largely eliminates, for example, the negative effects of rust, hard water (Ca and Mg compounds in both carbonate and sulfate forms), oil emulsions, adhering organic and inorganic contaminants that form layers, and so on. The mechanical design of the PH485-K probe with a fixed cable is optimized for easy and quick installation of the probe in piping or in free-flowing streams. The PH485-M12 probe, equipped with a connector, is primarily intended for installation in the TS500 rod-type sensor and for industrial applications.

Optical measurements

Optical measurement devices are used to monitor the physical and chemical parameters of water using light-based and optical methods. They provide accurate and reliable data for assessing water quality in water management, industrial, and environmental applications.

Optical measurement of dissolved oxygen and water temperature

Devices for the optical measurement of dissolved oxygen and water temperature are used to accurately track the biological and physical parameters of water. They enable reliable monitoring and evaluation of water quality in water management, industrial, and environmental applications.

ESKO12 - Optical Dissolved Oxygen Sensor

ESKO12 - Optical Dissolved Oxygen Sensor

The ESKO12 sensor operates on the principle of measuring the intensity of radiation on the luminescent layer of the sensor’s measuring head, which is triggered by a short, high-energy light pulse generated by the sensor’s electronics. Oxygen atoms absorb the pulse energy that would otherwise be emitted as photons by the phosphor atoms; therefore, the concentration of dissolved oxygen in the measured solution is inversely proportional to the measured intensity of the luminescent radiation. The sensor also regularly measures the intensity of low-energy light reflected from the phosphor (which does not induce luminescence) and uses this measured value for the sensor’s self-calibration.

Optical turbidity measurement

Optical turbidity measurement devices are used to monitor water clarity and detect suspended particles. They provide reliable data for evaluating water quality in water management, industrial, and environmental applications.

S461 - Optical Turbidity Sensor

S461 - Optical Turbidity Sensor

The S461/T optical infrared sensor is designed for operational turbidity measurements in municipal and industrial wastewater treatment plants, for monitoring surface water pollution, and for various industrial applications.
