Additel 673

Digital Pressure Calibrator

The Additel 673 is a digital pressure calibrator with measurement ranges up to 60,000 psi depending on configuration. It provides pressure accuracy options of 0.02 percent or 0.05 percent of full scale or 0.1 percent of reading based on model. The instrument measures gauge absolute differential and barometric pressure using an internal sensor and built‑in barometer. It supports electrical measurement with mA and V functions and 24 V loop power for device calibration.
