Th-9020 mercury calibrator is used to output a certain concentration of elemental mercury standard gas. It can be used to calibrate mercury analyzer and online system calibration. It can be completed by preset programming or user random operation. Because of the particularity of mercury, there is no cylinder gas of elemental mercury in China. The mercury calibrator can also be used as elemental mercury gas distributor, which can output 0.5-50 μ g / m3 elemental mercury gas and provide standard gas for laboratories or other research institutions.
The basic principle of the product is that the zero gas enters the mass flowmeter through the control valve to control the flow, and then enters the constant temperature infiltration furnace to blow out the mercury vapor. The blown mercury vapor is mixed with zero gas in a certain proportion to produce standard gases of different concentrations.
