Simple, Cost-Effective Pressure Decay Testing

Sentinel C20WE leak detection systems come in pressure decay and vacuum decay test options and is configurable to meet your requirements for pressure range and reject rate. An intuitive interface and multi-language software make the system global-friendly. The Sentinel C20 line of leak testing equipment has a low-maintenance design and delivers superior performance for testing applications ranging from consumer goods to medical or automotive.

Sentinel C20WE leak test equipment has a "Quick Test" feature that provides a highly reliable test on all parts while shortening the test portion of the cycle time by up to 80%. Throughput on existing test systems can be increased without major investment in fixtures, tooling, or operators. On systems that are already running shortened cycle times for all parts, the risk of accepting marginal reject parts is reduced.
