LG Sonic launched a new high-precision PO4 sensor and phosphate analyzer during WEFTEC 2021 in Chicago, IL. The product is the result of a joint project with the University of Dublin City. After years of research and development, this instrument is positioned as the most innovative in its family:
- It measures phosphate at different depths, generating a complete vertical profile of the concentration of nutrients in the water, optimizing environmental control.
- It allows each sample to be taken automatically, facilitating the detection of seasonal changes and reducing equipment downtime.
- Its winch system adjusts the configuration and measurement channels according to the applications and user requirements.
- It includes a peristaltic pump and resistant tubes that guarantee safe operation, even under different pressure and temperature levels.
- The possibility of minimal reagent and waste disposal extends the life of the instrument, reducing maintenance costs.
- Chemicals remain contained within the system, ensuring the safety of the environment and the operator.
Importance of phosphate in water
Nutrients such as nitrogen and phosphate are essential in any aquatic ecosystem. However, excess levels disrupt the natural water cycle and have a negative impact on environmental safety. Harmful algal blooms depend on PO4 levels, so continuous measurement is crucial for quality control.
Technological innovation of the analyzer
According to Dr. Margaret McCaul, principal investigator of the project, “phosphate levels in water were measured by manual collection and laboratory analysis, a costly and inaccurate method.”
LG Sonic’s new optical analyzer improves this process with an automatic detection system and integrated calibration. “Real-time monitoring provides reliable, high-precision data with the temporal and spatial resolution necessary to understand changes in nutrient levels within the water body,” McCaul added.
The equipment combines LED optical technology, 3D microfluids, and IoT communications, allowing for flexible installation, remote diagnostics, and configuration tailored to the type of application. The instrument calibrates itself automatically during each measurement, ensuring consistent results within its operating range.

Accuracy, operation, and maintenance
The PO4 sensor uses the yellow method, providing highly accurate readings across a wide range of concentrations. Its lab-on-chip technology reduces maintenance costs, and reagents are easily replaced using a secure dosing system.
Integrated diagnostics alert you to potential deviations or detection limits, while automatic calibration keeps the instrument running without interruption. Thanks to this combination of function, form, and precision, the system delivers consistent results even after long periods of use.
Its optical design detects color variations associated with phosphate concentration in each sample, sending the results via digital communications to the MPC-View software. The system also measures temperature, pressure, and other water quality parameters in real time, ensuring continuous and safe operation.
Results, installation, and quality control
During installation testing, the PO4 phosphate sensor demonstrated high stability and accuracy in different environments. Each channel of the system is optimized to provide continuous information on nutrient input and output, allowing complete control of the process.
The equipment includes diagnostic options and safe reagent disposal, while the optical laboratory system automates color detection and internal dosing. In addition, its modular structure offers great flexibility of use and easy installation, reducing downtime.
The sensor was field-tested for six months, confirming its durability and accuracy under variable pressure conditions. The results demonstrated a linear and stable correlation between the PO4 sensor measurements and the values obtained in the laboratory.
Integration, sustainability, and offering
The monitoring system integrates with MPC-View software and the Prognosys platform, providing comprehensive information on water quality. The user interface makes it easy to use, configure, and track data.
This autonomous instrument reduces operating costs, optimizes environmental safety, and minimizes the use of chemicals. Its smart design allows for remote maintenance, extending the life of the equipment.
