The Sentinel C20WE (World Edition) is a high performance, low cost, quality pressure decay leak detection instrument. Its small packaging enables the C20WE to integrate easily into product line testing applications. The Sentinel C20WE is easy to configure. The high flow valve option design reduces cycle times by filling and exhausting the part up to five times faster. It is excellent for high speed and/or big volume applications.

"Quik Test" feature, incorporated into the Sentinel C20WE, 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 which are already running shortened cycle times for all parts, the risk of accepting marginal reject parts is reduced.
