Brief introduction WN-20 online atmosphere of mercury detector is a smart mercury detector, MCU, data storage, automatic drawing working curve and other functions into together powerful mercury detection instrument. This instrument by cold atomic absorption spectrometry, catalytic device through the patent, and the wavelength 253.7 nm ultraviolet has strong absorption in a certain range, the concentration of mercury and absorption is proportional to the value, fits the bill law. Direct measurement of the content of mercury in flue gas, direct reading measurement concentration. At the same time, the total amount of ionic mercury and atomic mercury in atmosphere and smoke were measured. Using the most advanced PLC technology, the entire system on line automatic control, stable and reliable operation. High efficiency catalytic converter to convert ion mercury into atomic mercury. Heating sampling and filtering method. Removal of smoke and dust from flue gas. The catalytic converter is made of special material to ionic mercury into mercury atoms. Double beam measurement mode, automatic counter blowing cleaning function. Ensure measurement accuracy. Features Large screen color touch screen. Built in mercury standard curve, the user can automatically calibrate and automatically store the working curve is very convenient. Using single chip microcomputer control and calculation technology, direct display: mercury concentration of ng/ml, temperature, humidity. Does not require manual calculation. Instrument has a storage function, the measurement data will be automatically stored. Instrument has data query function, can directly query the date, time, measured value. Technical parameter 1 measurement principle: cold atomic absorption method. 2 automatic calculation of the concentration of mercury directly read, do not require users to convert. 3 measurement range: 0-100ng/ml (concentration can be customized according to user requirements). 4 minimum detection limit: 0.02ng/ml 5 linear correlation coefficient: R = 0.995 6 at the same time display: mercury concentration of ng/ml, temperature, humidity *. 7 color touch display, time date memory function *. 8 data query function, data storage 256 groups. 9 instruments have a working curve calibration function, according to the user needs to automatically save the working curve, the next time the boot directly using the direct measurement of the last curve. 10 flow range: 1.5L/min 11 power supply voltage: 220V+10% 12 instrument appearance size: 600 x 360 x 1100mm3 13 using ambient temperature: 0-40
