The Sentinel I28 is designed to deliver an accurate, reliable, and repeatable leak test measurement in a durable, proven platform. The Sentinel I28 is flexible and customizable and can be easily configured to meet the requirements of your test. Manufacturers can choose from a vast array of test types and options for pressure, flow, or vacuum testing, along with many other customizations.
The I28 can be integrated with a PLC or operate on its own with individual and linked tests in a user-programmed sequence. Combined with its ability to control up to 5 tooling motions, one instrument can control the operations of a test stand and replace a PLC for a cost-effective approach to testing.
