Application Scope
The TH-9020 mercury calibrator is used to output a certain concentration of elemental mercury standard gas, which can be used for calibration of mercury analyzers and online system correction, completed through preset programming or random user operation. Due to the special nature of mercury, there is no elemental mercury cylinder gas in China. The mercury calibrator can also be used as an elemental mercury gas distribution device, capable of outputting 0.5~50μg/m³ elemental mercury gas, providing standard gas for laboratories or other research institutions.
The basic principle of this product is that zero gas enters the mass flow meter through a control valve to control the flow, then enters the constant temperature permeation furnace to blow out mercury vapor. The blown mercury vapor is mixed with zero gas in a certain proportion to produce standard gases of different concentrations.
Instrument Features
•Uses imported permeation source as standard gas source, high-precision temperature control device; ensures stable gas source;
•Uses high-precision digitally controlled mass flowmeter to ensure gas distribution accuracy;
•Special treatment of internal gas path of the instrument;
•Uses 7-inch touch screen, beautiful and elegant.
