Online atmospheric mercury detector

WN-20Online atmospheric mercury detector

1： Product Description of Online Atmospheric Mercury Detector

The online atmospheric mercury detector has functions such as data memory storage, built-in mercury detection standard curve, and direct reading of concentration. At present, domestic manufacturers only have chemical reduction mercury detectors, which cannot meet the requirements of online detection,Our company has collaborated with Tsinghua University to develop an instrument for directly measuring the mercury content in industrial pollution emissions online. The mercury in industrial emissions is directly measured through a catalytic device, with automatic storage of working curves, direct reading of mercury concentration, and the ability to store data, dates, temperature, and humidity. No need for users to repeatedly create work curves.

2： Principle of online atmospheric mercury detector

The online atmospheric mercury detector is the latest intelligent mercury detector launched by our company. It combines functions such as microcontroller, data storage, and automatic drawing of working curves into a powerful mercury detector. This instrument adoptsUsing cold atomic absorption method and patented catalytic device,And for wavelength253.7nmUltraviolet radiation has a strong absorption effect, and within a certain range, the concentration of mercury is directly proportional to the absorption value, in accordance with Beer's law. Directly measureMercury in flue gasThe content can be directly read and measured for concentration.

l Simultaneously measure the total amount of ionized mercury and atomic mercury in the atmosphere and flue gas.

l Adopting the most advanced technologyPLCTechnology, online automatic control of the entire system, stable and reliable operation.

l An efficient catalytic converter converts ionized mercury into atomic mercury.

1. Heating sampling and filtering method. Remove smoke and dust from the flue gas.

2. The catalytic converter made of special materials converts ionized mercury into atomic mercury.

3. Dual beam measurement method, automatic periodic blowback cleaning function. Ensure measurement accuracy.

3： Scope of application of online atmospheric mercury detector

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, and chemical industry. Especially suitable for all-weather mercury measurement in online flue gas emissions.

On site testing of incineration flue gas emissions, industrial emissions, chemical decomposition, etc.

4： Characteristics of online atmospheric mercury detector:

l Large screen color touch screen display.

l The built-in mercury detection standard curve allows users to calibrate and automatically store the working curve, which is very convenient.

l Using microcontroller control and computing technology, directly displaying: mercuryconcentrationng/mlTemperature and humidity. No manual calculation is required.

l The instrument has a storage function to store measurement dataauto-save.

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