Profile: ATEQ UK is a supplier of automatic leak testing machines and leak test systems for assembly lines or laboratories. We develop a whole range of industrial control equipment ranging from electrical testers to pressure and flow calibrators as well as pressure & flow calibration services. Our precision volume tester has differential pressure transducer. Inside it, a specifically designed fixture lays two chambers. One that matches as closely as the shape of used part called test chamber and another of exactly the same volume of the first chamber when a part is inside it, called reference chamber. The instrument starts by filling up at a given pressure two internal volumes, one for the reference circuit and one for the test circuit. Then it isolates itself from the pressure line as well as isolates each circuit from one another. In the final stage of the test, the instrument empties each internal circuit into both chambers. We also build an extensive range of functional test rigs for various industries ranging from appliances to automotive.
