Abstract
Canister tester for rapid testing of the contents of a pressurized canister containing fluid or gaseous matter. Incoming canisters are placed into a dual rotary canister test bed and are revolved about the canister test bed axis to mix the canister contents prior to pretest purging and final test stations. A load mechanism loads canisters into the dual rotary canister test beds for testing. An eject mechanism ejects tested canisters from the dual rotary canister test beds into an off-load star wheel. Unsatisfactorily tested canisters are ejected prior to placement on an output conveyor.
