Additel ADT760A / ADT760S Series Pressure Calibrator

The Additel ADT760A / ADT760S series pressure calibrator is a high-performance automatic handheld pressure calibrator designed for precision and portability in the field. Weighing less than 4 lbs (1.8 kg), this integrated device replaces bulky manual pumps with a built-in electric pump, internal controller, and a precision pressure sensor. Optimized for instrumentation technicians, the ADT760A offers a seamless user interface via a new capacitive touch screen, allowing users to generate and control pressure by simply entering the desired setpoint. With four distinct channels, including internal pressure, external pressure (2 channels) and electrical measurement, it serves as a comprehensive tool for pressure calibration and maintenance of critical process infrastructure.

Engineered to enhance workflow efficiency, the ADT760A introduces significant technical upgrades over its predecessor, including an upgraded range (375 psi), an improved touch screen, a full-capability HART field communicator, and a non-PC version option (ADT760S). A new accessory is also available: an attachable Contamination Prevention System to protect internal components. This multifunction documenting process calibrator supports automated task documentation and data logging, reducing the need for manual record-keeping, as well as HART communication capabilities for advanced pressure sensors. Whether performing routine transmitter calibrations or complex field diagnostics, the Additel 760A provides a robust, automated solution that bridges the gap between lab-grade accuracy and rugged field reliability.

The ADT760A series includes three configurations for different pressure ranges. The 760A/760S-LLP is intended for low-pressure calibration, supporting ranges up to ±30inH₂O with accuracy to 0.05% full scale and allowing gauge or differential measurements, with optional modules extending to lower ranges. The 760A/760S-D covers mid-range applications from -12.5 to 35psi with accuracy up to 0.01% full scale and supports both gauge and differential measurements, including lower-range options for improved precision. The 760A/760S-MA operates from vacuum up to 375psig with accuracy up to 0.01% full scale, includes a barometric reference, and supports both gauge and absolute pressure measurements.
