The Additel 760A 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.
ADT760A/760S-LLP
The 760A/760S-LLP is designed for low pressure calibration and comes with a built-in pressure module of your choice. The maximum range module compatible with the 760A/760S-LLP is ±30 inH2O (±75 mbar) and provides an accuracy to 0.05%FS (see ordering information for available configurations). Additional internal pressure modules (ADT155) are available, with ranges down to ±0.25 inH2O (±0.62 mbar). Measurements can be made in gauge or differential mode.
ADT760A/760S-D
The760A/760S-D gives you differential and gauge pressure, but at a higher pressure range than the 760A/760S-LLP. Spanning a range of -12.5 to 35 psi (-0.86 to 2.5 bar) and with an accuracy up to 0.01%FS, the 760A/760S-D is an ideal solution to cover common gauge and differential pressure measurements. The Additel 760A/760S-D comes with an internal module of your choice, with maximum pressure to 35 psi. Lower pressure configurations down to ±10 inH2O differential can be purchased to improve accuracy at lower pressures.
ADT760A/760S-MA
The 760A/760S-MA generates and controls pressure from vacuum pressures up to 375 psig (25 bar.g) with an accuracy up to 0.01%FS. Equipped with a built-in barometric reference, each unit can switch between gauge and absolute pressure types. A variety of internal sensors (ADT155) are available which offer lower pressure ranges for improved performance.
The data logging capability is only available on the ADT760A models. Please see the selection guide here for more info.
