Use this flowmeter to create customized gas compositions
This company’s mass flowmeters and contollers now feature its Gas Select 5.0 firmware and the newly added Gas Select Composer module, which allows users to create highly accurate mixed-gas compositions (photo). Version 5.0 of the firmware includes an expanded library of up to 130 preloaded gas calibrations. In addition to pure gases, Gas Select 5.0 also includes numerous gas mixtures that are commonly used in bioreactor, welding, power, refrigerant and medical applications. The newly added Gas Composer module gives users the ability to quickly program and store up to 20 customized gas compositions directly on the mass flowmeters and related controllers. Using an integrated digital display, users can define gas compositions to 0.01% for each of up to five constituent gases. Up to 20 gas mixtures can be created and stored simultaneously on each device.— Alicat Scientific, Tucson, Ariz.
