SDL 205 Standard gas generator
The SDL 205 standard gas generator realizes proportional dilution of standard gas and produces standard gas with a preset volume concentration. The preset volume concentration is not higher than the standard gas concentration. It can also continuously generate special calibration gases that are difficult to store (such as H₂O, NH₃, HCl, HF, HgCl₂, etc.). The humidity concentration can reach 40%. Other calibration gases are determined by the reagent concentration.
