Get Flexible Leak Testing in a Standard Instrument

The Sentinel Blackbelt is a high-precision benchtop instrument providing unmatched flexibility in a proven, standard platform. Popular for medical device leak, flow, and blockage testing and other applications, the Blackbelt can reduce the footprint, complexity and overall cost of your leak test.

The instrument is configured to meet your test requirements. Choose from a vast array of test types and options of one, two, three or four sequential test ports along with many other configurable capabilities.
