Qubit Systems manufactures gas control systems. These systems can regulate gas concentration (CO2, O2, CH4, H2, RH) in a chamber or a cabinet. We can control flow of gas through a multichannel gas measuring system so multiple samples can be measured with one set of gas analzyers. We provide customized setups to meet user’s applications. Systems for regulation of gas concentration employ a digital gas controller which uses feedback regulation of a solenoid valve to release a minor gas in the background of a major gas. In a multichannel system where multiple samples are being measured for gas exchange, we employ a gas switchers (up to 4 or 8 channels). Qubit Systems also provides control of dissolved gases in our Aquatic Control Systems
