At Additel, innovation and continuous improvement are part of our company's culture and the products we introduce. When we set out to deliver the Additel 761A series calibrators, we knew we 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!
ADT761A-APXR Precision Accuracy Options
The Additel 761A series includes a precision accuracy option which provides an accuracy of 0.01%FS. This calibrator option includes a single non-removable sensor and can measure absolute and gauge pressures. Model configurations are available from 15 to 1,000 psig (1 to 70 bar.g).
