Industrial C-20C Pressure Decay Test System

The Cincinnati Test Systems Sentinel C-20C Pressure Decay Test System is an industrial leak-test instrument that uses the pressure-decay method to verify the integrity of sealed parts, operating in a 0–15 psi test range. It provides RS232 data readout and control and runs on 24 VDC power, enabling integration with test benches and data-acquisition systems. This variant is marketed as “No Bulb,” with listings noting the absence of a built-in indicator bulb while retaining the core C-20C test capability. The Sentinel family from CTS is CTS’s line of pressure-decay leak testers designed for reliable, repeatable leak testing of sealed components in production settings. Typical applications include testing enclosures and assemblies in industrial manufacturing where fast, deterministic leak detection is needed.
