Fluorescence Method Chlorophyll a Online Analyzer Manufacturer: Fengtu Technology

Fengtu's fluorescence method chlorophyll a online analyzer detects chlorophyll content based on fluorescence characteristics and is specifically designed for online monitoring of rivers, lakes, and ponds. The instrument is easy to operate, stable in performance, and accurate in measurement, suitable for long-term continuous monitoring of algal concentration in water bodies.

The fluorescence method chlorophyll a online analyzer is an analytical instrument based on optical principles, specifically used for online detection of chlorophyll a content in water bodies. Its working principle is mainly based on the fluorescence characteristics of chlorophyll a molecules. When a light source of a specific wavelength illuminates the water body, the chlorophyll a in the algal cells absorbs the light energy and emits fluorescence of a longer wavelength. Under specific conditions, the intensity of the emitted fluorescence is directly proportional to the concentration of chlorophyll a in the sample. By accurately detecting the intensity of this fluorescence signal with a high-sensitivity optical sensor, quantitative analysis of chlorophyll a concentration can be achieved. This method has the characteristics of high sensitivity and fast response.

As the manufacturer of this instrument, Fengtu's products typically adopt an integrated design. The standard equipment consists of an optical detection unit, a fluid control unit, a data processing unit, and a communication module. The optical detection unit includes an excitation light source, a filter, and a photodetector. The fluid system is responsible for introducing the water sample to be tested into the measurement chamber and discharging it after measurement. The data processing unit controls the entire measurement process and is responsible for signal acquisition, calculation, and storage. The instrument supports standard communication interfaces and can upload real-time monitoring data to a monitoring platform.

This analyzer is mainly used in the field of algal monitoring in natural and artificial water bodies. At water quality monitoring stations in rivers, lakes, reservoirs, and other surface water bodies, it can be used as a fixed online device for long-term operation, reflecting changes in algal biomass in the water body in real time and providing key parameters for eutrophication early warning. At the water intake or pretreatment stage of water treatment plants, monitoring chlorophyll a helps to warn of the risk of algal blooms and ensure water supply safety. In areas such as pond aquaculture and landscape water management, the instrument can also be used for daily water quality monitoring to guide the timely implementation of ecological regulation or treatment measures.

The instrument is easy to operate. Users typically only need to complete the pipe connections and power supply connection, and set basic parameters such as measurement intervals via a touchscreen or remote platform to start automatic continuous monitoring. Routine maintenance mainly includes regular cleaning of the optical window and calibration. Its stable performance is attributed to a precise temperature control system, a stable light source design, and a pollution-resistant optical path structure, enabling it to adapt to the variable operating environments outdoors. The instrument boasts high measurement accuracy and a wide measurement range, meeting the needs for detecting a wide range of concentrations from oligotrophic to eutrophic water bodies.

As an online monitoring device, its core value lies in achieving automated and continuous measurement of chlorophyll-a levels. Compared to traditional manual sampling and laboratory analysis, it provides high-time-resolution data sequences, accurately capturing diurnal variations and short-term fluctuations in algal concentration, compensating for the shortcomings of intermittent sampling that may miss peak data. The long-term continuous data accumulation is of great scientific significance for studying algal growth patterns, assessing the ecological health of water bodies, and validating algal bloom prediction models.

As a manufacturer, Fengtu not only provides standardized instrument products but also typically offers supporting services such as data management software, installation and commissioning, and technical training, forming a complete monitoring solution. This allows the instrument to be effectively integrated into various water quality automatic monitoring stations or environmental Internet of Things systems, becoming an important component of water environment early warning and monitoring networks.
