The Gas-SelectX gas-selection feature of the FT1 thermal mass flowmeter (photo) has been expanded to include more pure gases. The 11 available pure gases for the device are: air, argon, butane, carbon dioxide, helium, hydrogen, methane, natural gas, nitrogen, oxygen and propane. Additionally, the Gas-SelectX feature includes a new three-gas mix option, which allows the user to choose any three pure gases (excluding natural gas) from the menu and mix them in 1% increments to total a 100% custom mixture. These features make the FT1 suitable for measuring digester gas, liquefied petroleum gas (LPG) and a variety of biogases. — Fox Thermal Instruments, Inc., Marina, Calif.
