Sentinel C28DP Differential Pressure Instrument

  • Sentinel C28DP Differential Pressure Instrument

The Sentinel C28DP Differential Pressure leak test instrument provides the same exceptional performance of our C28WE leak test instrumentation, with the newly designed Differential Pressure decay circuit and differential pressure transducer. The Sentinel C28DP uses a 32-bit processor, 24-bit A/D technology, and advanced algorithms to deliver fast, repeatable results.
