The beer carbonation tester has an 11 ounce acrylic canister with a handy label noting the appropriate CO2 volume based on your temperature and pressure reading. The tester’s cap has easy to grip knurling. The pressure gauge includes a protective rubber boot for additional durability. Each Tester comes with a cushioned carrying case, as well as inlet and outlet hoses with quick disconnects.
