ETCG-2A IntelligentMicrocomputer Cold Atomic Absorption Mercury Analyzer

1： Principle of Intelligent Microcomputer Cold Atomic Absorption Mercury Analyzer

The microcomputer cold atomic absorption mercury detector is a newly launched intelligent mercury detector by our company. It combines functions such as microcontroller, data storage, and automatic drawing of working curves into a powerful mercury detector. This instrument adopts the cold atomic absorption method, based on the fact that elemental mercury can evaporate into mercury vapor at room temperature without heating, and has a strong absorption effect on ultraviolet light with a wavelength of 253.7nm. Within a certain range, the concentration and absorption value of mercury are proportional, which conforms to Beer's law. Directly measure the mercury content and read the measured concentration.

2： Application scope of intelligent microcomputer cold atomic absorption mercury analyzer

This instrument is suitable for measuring the mercury content in water, air, soil, food, cosmetics, chemical raw materials, and other industries such as environmental monitoring, health and epidemic prevention, tap water, and chemical industry.

3： Intelligent microcomputer cold atomic absorption mercury analyzer features:

• Equipped with imported sensors and a large color touch screen display, the operation is simple and convenient.
• The built-in mercury detection standard curve allows users to calibrate and automatically store the working curve, which is very convenient.
