Cincinnati Test Systems I21-S-100 Pressure Decay Instrument

The Cincinnati Test Systems Sentinel I21-S-100 Pressure Decay Instrument is a purpose-built leak-detection tool designed to verify the integrity of parts and assemblies through pressure-decay testing, delivering reliable, repeatable measurements in manufacturing environments. In a typical cycle, the instrument charges the part to a defined pressure, seals the chamber to isolate the pressure, and continuously monitors the resulting decay over a fixed interval, with results presented as a leak rate, delta P, or delta P/∆T to support pass/fail decisions. As part of the Sentinel family, the I21-S-100 is designed for seamless integration into automated test benches and production lines, with CTS software for test programming, data logging, and exporting results to standard quality systems, dashboards, or manufacturing execution systems. Because configurations vary by installation, CTS data sheets for the I21-S-100 define the available pressure ranges, test durations, sensor performance, and accessory options for each configuration, ensuring you select the precise setup that aligns with your leak-testing requirements and workflow.
