Nearly all water quality monitoring instruments are considered independent, such as turbidity meters, pH meters, conductivity meters, dissolved oxygen meters, etc.

Their setup and maintenance procedure could be more transparent. High intellectual abilities will be the future development trend.

Here, we will focus on a Multiparameter Water Quality Meter.

What is the Multiparameter Meter all about?

Primarily, the water quality multiparameter is a small sonde or sensor that can measure temperature, pH, turbidity, dissolved oxygen in one instrument, and conductivity.

This equipment is unified for power supply and communication, which simplifies the electrical structure significantly.

Simultaneously, because of the high integration, the instrument’s installation space is minimized to the greatest extent possible, and the installation’s portability is enhanced.

It reflects the quality of the water sample, forecasts the trend of water quality development, and provides a scientific foundation for water pollution planning, development, management, utilization, and prevention.

What are the Multiparameter Meter Applications?

Multiparameter Sondes can be found in many water quality projects. They can be found in every aspect of our lives and play an important role.

• River and lake water quality inspections

• Heavy industry and mining entities, sensors of urban sewage discharge

• Water quality monitoring in petrochemical, chemical, power generation, pharmaceutical, food, electronic, and water plants, etc. 

• Water quality inspection in urban parks

What is the Future of Multiparameter Meter?

As previously stated, the monitoring method for multiparameter meters will become increasingly convenient. Let’s examine how it can become a part of your daily life-

Sensor’s efficiency: 

The pre-manual detection method is time-consuming and has an impact on secondary pollution. Detection technology must combine multiple technologies to improve sensor efficiency significantly in the future.


At the moment, there are far too many manual detection processes, and even with instrument detection, personnel intervention is required regularly. Humans will reduce maintainability in the future as AI technology advances, including chemical oxygen demand calculation via the Internet of things.

Online real-time detection: 

When compared to manual detection, detection is relatively slow. With the advancement of the Internet of Things and 5G technology, online real-time monitoring should be the primary focus of Multiparameter Sondes.

Principle of detection:

Optical detection, as opposed to reagent detection, is a future development direction. There are still some errors when compared to single-band detection. Multi-spectrum detection can significantly improve detection efficiency.

FAQs- Multiparameter 

• What is the definition of a Multiparameter Water Quality Meter?

It is a portable water meter that measures various parameters of water quality. It includes a microprocessor-based multi-sensor probe for measuring critical parameters such as pH/pX, DO, conductivity, and temperature.

• Is the Multiparameter’s detection of the type of water quality fixed?

Of course not; it detects five major water quality indicators (dissolved oxygen, turbidity, bioindicators, nitrates, pH scale, and water temperature) and can expand to see additional water quality parameters based on environmental conditions.
