Mercury Analyzer

Principle of mercury analyzer

Our company has recently launched a mercury analyzer, which adopts the national standard method of 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.

Scope of application of mercury analyzer:

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.

Characteristics of 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. The absorbance can be directly displayed on the interface, and the correlation coefficient R can be automatically calculated, 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 be connected to a Bluetooth printer for printing.

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 according to the K value.

Technical indicators of mercury analyzer:

1. Measurement principle: Cold atomic absorption method; (National standard)

2. Automatically calculate and directly read the concentration of mercury without the need for user conversion.

3. Measurement range: 0-5/10ng/ml (dilution is required for measurement above 10ng/ml);

Temperature: -20 ∽ 60 ℃. Humidity: 10-95% RH;

4. Detection limit: 0.2ng/ml;

5. Linear correlation coefficient: R ≥ 0.995;

6. Simultaneously display: mercury concentration ng/ml, temperature, and humidity;

7. Color touch screen display with time and date memory function;

8. It has data query function and stores 256 sets of data,

9. The instrument has a working curve calibration function, which automatically saves the working curve according to the user's needs. The last curve can be directly used for measurement the next time it is turned on; Automatically display the absorbance value and calculate the correlation coefficient R. The measurement data can be corrected slightly by the K value;

10. Flow regulation range: 0-2.5L/min;

11. Power supply voltage: 220V+10%;

12. Instrument dimensions: 410 × 400 × 150mm;
