In the current era of rapid technological development, Multi parameter analyzer, as an advanced detection device, are widely used in many fields, providing key data support for our production, life, and scientific research.
1、 Working principle revealed
The multi parameter analyzer can simultaneously measure multiple parameters, mainly due to its integrated multiple sensing components such as electrodes, optical sensors, temperature sensors, etc. These sensors are like the “antennae” of an analyzer, with unique sensitivity to different parameters.
Taking the common water quality multi parameter analyzer as an example, the pH sensor determines the pH value by measuring the concentration of hydrogen ions in the water sample, utilizing the ion reaction between the water sample and a special sensitive membrane inside the sensor;
Dissolved oxygen sensors measure the dissolved oxygen content in water samples based on electrochemical principles by detecting the current generated by the oxidation-reduction reaction of oxygen on the electrode surface;
Turbidity measurement often uses the principle of scattered light. When a beam of light shines on a water sample, suspended particles in the water scatter the light, and the instrument infers turbidity by detecting the intensity of the scattered light.
The measurement of conductivity also involves inserting two electrodes into a water sample to apply voltage, measuring the current passing through the water sample, and calculating the conductivity value based on Ohm’s law.
In the colorimetric multi parameter water quality analyzer, photoelectric conversion technology is also used. The light source emits light of a specific wavelength to irradiate the sample, exciting chemical substances to produce color reactions.
The photoelectric converter then converts the color signal into an electrical signal. Finally, the data processing system amplifies, filters, and A/D converts these electrical signals to present the measurement results in digital form.
It can even comprehensively analyze multiple parameters according to preset algorithms and generate a comprehensive evaluation report.

In drinking water monitoring, multi parameter water quality analyzers can detect and evaluate water sources to ensure the safety of drinking water. In water plants, purified water plants, sewage treatment plants, etc., the health status of water bodies is evaluated by monitoring indicators such as dissolved oxygen, pH value, turbidity, chemical oxygen demand (COD), ammonia nitrogen, etc., guiding the water treatment process, providing a basis for environmental monitoring, and ensuring that the discharge water quality meets the standards.
（2） Environmental monitoring
Used for monitoring the atmospheric environment, analyzing air quality, and assisting in the study of climate change and environmental pollution levels.
For example, monitoring the concentration of pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter (PM2.5, PM10) in the air, as well as monitoring greenhouse gases such as carbon dioxide and methane, provides a data basis for the formulation of environmental protection policies.
（3） Pharmaceutical industry
Strictly controlling parameters such as temperature, humidity, pH value, etc. during the drug production process is crucial to ensure drug quality and compliance with regulatory requirements.
The multi parameter analyzer can monitor these key parameters in real-time, ensuring that drug production is carried out in a suitable environment and guaranteeing drug safety and efficacy.
（4） Food industry
Used to measure indicators such as acidity, salinity, moisture content, and microbial content in food to ensure food safety and quality.
From raw material procurement and testing to production process control, and then to finished product quality inspection, multi parameter analyzers run through the food industry chain, safeguarding the safety of consumers’ tongues.
（5） Life Science Research
In fields such as cell biology and molecular biology, detecting environmental factors in cell culture, such as temperature, pH value, oxygen concentration, carbon dioxide concentration, etc.
Provide suitable conditions for cell growth, assist researchers in gaining a deeper understanding of cellular physiological characteristics and life activity patterns, and promote the development of life science research.
