Sentinelâ„¢ I28

The Sentinel I28 is the world’s most advanced multi-functional test instrument on the market. The I28 features a standard valve manifold design tested with over 40,000,000 cycles. CTS pairs this manifold with a new high performance pressuretransducer that reduces test cycle and improves accuracy and repeatability.
