Additel ADT685 Digital Pressure Gauge

Overview

The Additel ADT685 is a professional digital pressure gauge engineered for precision measurements in field and laboratory environments. Built around advanced microprocessor technology and state-of-the-art silicon pressure sensors, the ADT685 combines a modern 3.4-inch touchscreen interface with full temperature compensation to deliver reliable performance across variable operating conditions. This gauge is available in multiple accuracy classes—0.02%, 0.05%, or 0.1% of reading—with pressure ranges extending up to 60,000 psi (4,200 bar).

Every ADT685 model includes a built-in barometer sensor and selector switch to measure either gauge or absolute pressure, making this single instrument capable of three measurement functions: gauge pressure, absolute pressure, and atmospheric pressure. The rugged IP67-rated design protects against dust and moisture in demanding work environments.
