The Sentinel I-28 is the world’s most advanced multi-functional test instrument on the market. The I-28 features a standard manifold design tested with over 40,000,000 cycles. CTS pairs this manifold with a new high performance transducer that reduces test cycle and improves accuracy and repeatability.
