At Additel, innovation and continuous improvement are part of the company's culture and the products they introduce. When Additel set out to deliver the Additel 761A series calibrators, they knew they needed to provide breakthrough improvements and additional value to the existing line of calibrators (Additel 761 series). The ADT761A has many improvements: increased pressure range to 1,000 psi (70 bar), removable internal pressure modules, optional precision models to 0.01%FS, increased speed to pressure, ability to read two external pressure modules, touch screen display, Wi-Fi, Bluetooth, and Ethernet communications, double the original battery life, and more!

AMS Driver

The Calibration Assistant SNAP-ON application interfaces with documenting calibrators to manage the calibrations of HART, Foundation fieldbus, IEC-approved WirelessHART®, and conventional devices. It allows you to easily group your devices into test schemes and calibration routes for maximum efficiency.

Transfer data between your calibrator and AMS Device Manager to eliminate manual records and the possibility of errors. By using the ADT761A self-documenting calibrator, you can also automatically check As-Found/As-Left information into the AMS Device Manager database. Access the calibration history of each device as well as generate calibration certificates and reports if you need hard copy documentation. The Calibration Assistant SNAP-ON application gives you more accurate calibration data by reducing reporting errors and extending the time between calibrations.

ADT761A-LLP
The Additel 761A-LLP is designed for low pressure calibration and comes with a ±30 inH2O (±75 mbar) high range module and a low range module of your choice ranging from ±20 inH2O to as low as ±0.25 inH2O (±50 to ±0.62 mbar). This unit has an accuracy of 0.05%FS with control stability better than 0.005%FS. All measurements can be made in differential or gauge pressures.

ADT761A-D
The Additel 761A-D also provides differential and gauge measurement which covers the range of -13.5 to 35 psi (-0.95 to 2.5 bar). This unit comes with a CP35 module (-13.5 to 35 psi) and one low range module of your choice rangeing as low as ±10 inH2O (25 mbar). Each ADT761A-D can be preconfigured with the modules that fit your need to give you the best precision at the pressures you perform calibrations.
