Additel 780

Pressure Calibrator

The Additel 780 is a bench‑top pressure controller with control ranges from vacuum to 3,000 psi depending on configuration. Control stability is specified to 0.003 percent of full scale with standard accuracy of 0.02 percent of full scale or optional precision accuracy to 0.01 percent of reading. The system supports gauge or absolute pressure measurement through interchangeable intelligent pressure sensors. Operation is fully temperature compensated from 0 °C to 50 °C.
