The Additel 760A / 760S series is available in three configurations to cover a wide range of applications:

• ADT760A/760S-LLP: Ideal for low-pressure calibration up to ±30 inH₂O (±75 mbar) with accuracy up to 0.05%FS, supporting gauge and differential measurements.

• ADT760A/760S-D: Designed for mid-range differential and gauge pressure applications, covering -12.5 to 35 psi (-0.86 to 2.5 bar) with accuracy up to 0.01%FS.

• ADT760A/760S-MA: Suitable for higher pressure ranges, from vacuum up to 375 psig (25 bar.g), with accuracy up to 0.01%FS and a built-in barometric reference.

Additional internal pressure modules (ADT155) are available to extend measurement capabilities and improve accuracy across lower pressure ranges. A dedicated Contamination Prevention System accessory is also available to protect internal components and ensure long-term reliability.

The Additel 760A / 760S Automatic Handheld Pressure Calibrator is a high-performance, fully automated solution designed for precise pressure measurement and calibration in both field and laboratory environments. Engineered for instrumentation technicians and calibration professionals, this compact device integrates a built-in electric pump, internal controller, and high-accuracy pressure sensor to eliminate the need for manual pressure generation.

Weighing less than 4 lbs (1.8 kg), the Additel 760A / 760S combines portability with advanced functionality, making it an ideal tool for on-site calibration, maintenance, and troubleshooting of critical process systems. Its intuitive capacitive touchscreen interface allows users to quickly generate and control pressure by simply entering a setpoint, significantly improving efficiency and reducing operator error.

Designed to streamline workflows, this multifunction calibrator features four independent channels: internal pressure, two external pressure inputs, and electrical measurement. The ADT760A model also includes data logging and automated task documentation, enabling users to record and manage calibration data without manual input. Additionally, integrated HART communication capabilities allow for advanced calibration of pressure transmitters, making it a complete documenting process calibrator.
