Mercury analyzer intelligent microcomputer cold atomic absorption mercury measurement equipment

One:Mercury analyzer intelligent microcomputer cold atomic absorption mercury measurement equipmentPrinciple

Cold atomic absorption method is a national standard method. Our company has recently launched a mercury analyzer that uses 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 of mercury is proportional to the absorption value, which conforms to Beer's law). Directly measure the mercury content and read the measured concentration.

Secondly:Mercury analyzer intelligent microcomputer cold atomic absorption mercury measurement equipmentScope of application

This instrument is used to measure the mercury content in water, air, soil, food, cosmetics, chemical raw materials. The same applies to industries such as health and epidemic prevention, environmental monitoring, chemical industry, and water supply

3： Characteristics of Cold Atomic Absorption Mercury Analyzer:

1. The instrument adopts ultraviolet sensors and a large color touch screen display

2. Built in mercury detection standard curve and K value correction, users can calibrate and automatically store working curves, making operation very convenient.

3. It can directly display absorbance on the interface and automatically calculate the correlation coefficient R, which is concise and clear.

4. Using microcontroller control and calculation technology, directly display: mercury concentration ng/l, temperature, humidity. No manual calculation is required.

5. The instrument has a storage function and automatically stores 256 sets of measurement data. Can import computer archives and print (requires software implementation)

6. The instrument has a data query function, which can directly query the measurement date, time, and measurement value.

7. If the customer makes a mistake and causes data disorder, they can directly click to restore the factory calibration settings, which is more user-friendly.

8. The linear offset of the measurement data can be directly corrected by the K value.
