Physical and Chemical Sensors

Water pollution by discharges impacts directly on the health of humans, as well as having secondary

socio-economic consequences on populations.

Hydroquo+ achieves rapid detection of pollutants by monitoring physical-chemical parameters that indicate water quality and protect the environmental state of natural water sources. We have extensive experience in handling potentiometric, polarographic and optical technologies.

Tracking sensors also optimize processes in wastewater treatment plants, aquaculture facilities and any sectors where water plays a significant role.

In order to study and monitor water quality, Hydroquo+ provides a wide range of products based on chemical sensors, electromechanical transducers, sensors for liquid level measurement and pressure sensors with different ranges.

Our monitoring solutions are available in various versions: submersible or surface mounted with power supply cable or wireless connection; they can be used in real time or through data loggers or PLCs, controlling pumps and alarms.

Various Applications

Monitoring water quality using potentiometric, polarographic and optical technologies.

Industrial Processes

Optimizing the efficiency of wastewater treatment plants, aquaculture facilities and any sectors where water plays a significant role.

Agricultural Sensors

Optimizing fertilization processes through early detection of crop stress caused by adverse environmental conditions.

Potentiometric sensors measure the potential difference between two sensors (indicating sensor and reference sensor) immersed in a solution. The indicator sensor provides the potential that is generated as a function of the concentration of specific ions. In contrast, the reference sensor has a known, stable potential, independent of the ions present in the solution. Potentiometric sensors are widely used for the measurement of pH, ORP and conductivity.

Spectro lyser

The spectro::lyser™ measures across the entire absorption spectrum from 190-750 nm and is used by many water utilities worldwide to monitor water quality. Due to its ability to analyze the entire absorption spectrum, the spectro::lyser™ is able to measure a large number of parameters in the water.

Depending on the application, spectro::lyser® UV measures an individual selection from AFS, TS, turbidity, color, TOC, DOC, BOD, COD, NO3-N, NO-3, HS-, O3, CLD, UV254, fingerprints, spectral -Alarms and temperature.

Dissolved oxygen

Based on fluorescence extinction measurement. The sensor membrane contains a luminescent compound that, when excited with blue LED light, emits red light. The more dissolved oxygen in the sample, the more this red fluorescence is quenched. The intensity and lifetime of the luminescence are inversely proportional to the oxygen concentration.


Optical sensors can measure the refraction of light in two ways. Firstly, light emitted by the LED is scattered proportionally by the turbidity of the sample. Secondly, by attenuation and absorption – the light emitted by the LED is absorbed, the amount of light that reaches the detector being inversely proportional to the turbidity of the sample.
