HBzhan Content Introduction: The algae counter is an intelligent algae counting analyzer that can quickly achieve clear imaging of algae, automatically classify and count algae by morphology, accumulate total numbers, and sort dominant algae, replacing manual microscopic counting and improving work efficiency and accuracy. Equipped with a database of multiple types of algae (blue-green algae, green algae, diatoms, naked algae, yellow algae, brown algae, dinoflagellates, dinoflagellates, gold algae, red algae, and diatoms) and thousands of algae identification and comparison libraries in China, it can intelligently match and search through morphology, keywords, taxonomy, common algae, etc., automatically analyze and identify the taxonomic genus of the tested algae, and assist those with insufficient knowledge of algae to learn and judge the possible categories and species of algae.
　　
　　Algae counterApplied to environmental protection, hygiene and epidemic prevention, tap water, chemical and other units, used for online monitoring of drinking water and measurement, monitoring and research of algae and plankton in rivers, lakes, oceans. Performance parameter report editing and printing: providing report writing templates, text input, print preview, data export: exporting algae statistical data to EXCEL.

The pollution of water sources is becoming increasingly serious, with eutrophication of water quality, outbreaks of algae, and pollution from algal toxins, all of which are endangering the environment and human health. While actively strengthening the creation of an environmentally friendly society, algae monitoring is gradually being carried out domestically. The algae counter replaces manual microscopic counting, improving work efficiency and accuracy.
　　
In recent years, algal blooms and red tides have occurred frequently, and reports of toxic algae are not uncommon, especially in some areas where algal outbreaks have caused pollution to urban residents' domestic water. The Ministry of Environmental Protection, Ministry of Water Resources and other departments have successively held work meetings, requiring monitoring units in various regions to organize forces to actively carry out algae monitoring.
　　
At present,Algae monitoringThere are mainly two methods: online monitoring and manual microscopy.
　　
Online monitoring: Common algae such as blue-green algae, green algae, diatoms, etc. contain chlorophyll a and produce fluorescence under excitation light of a certain wavelength. Fluorescence signals are collected by fluorescence detection instruments, and the fluorescence value is calculated. Using the proportional relationship between fluorescence signals and chlorophyll a concentration, different algae are distinguished based on their fluorescence reaction characteristics, and parameters such as chlorophyll a concentration and algal density in water are indirectly measured. This method uses in-situ monitoring, which is fast and simple, but the measured data is affected by various environmental factors such as temperature, light intensity, salinity, and water depth; Monitoring algae can only reach the phylum and cannot be specific to the genus or species, making it difficult to identify dominant species and resulting in significant deviations in monitoring results.
　　
Manual microscopy: Collect water samples, preprocess them, drop them onto a cell counting box, slice them, classify and count algae in 100 fields under a microscope, determine dominant species, and calculate algal density. The manual microscopy method can directly observe and count algae and identify their genera and species, but it cannot perform in-situ detection, takes a long time, and is prone to visual fatigue. There are also some errors in human judgment, and the operator needs to have certain knowledge and experience in algal taxonomy. However, algae monitoring in China started relatively late and has a weak foundation. Only a few research institutions in China are engaged in algae monitoring work, and the level of researchers varies greatly. There is a serious shortage of talents in the field of algae monitoring.
