Dynamic Gas Blender, DAS-2 (CAT#: STEM-C-2753-ZJF)

The Dynamic Gas Dilution Instrument is a standard gas dilution device developed in-house by our research institute, designed for preparing standard gas mixtures either online or in the laboratory. It comprises a flow control system, gas circuit control system, and electrical control system internally. Its principle involves precisely controlling gas flow to dynamically dilute high-concentration gas samples to the desired lower concentration gases.
