Additel 761A-LLP/D Instruments Automatic Pressure Calibration


Additel Automatic Pressure Calibration has been producing automatic pressure calibrators for years, we set new company standards to achieve greater customer satisfaction with our latest models. Our new options in the Automatic Pressure Calibration Additel 761A-LLP/D Series line offer greater flexibility in multi-range selection, multiple external pressure module management, and speed-to-pressure improvements.

Each of our Automatic Pressure Calibration Additel 761A-LLP/D Series is now conveniently transportable, as well as Bluetooth, Wi-Fi, and Ethernet enabled. All Automatic Pressure Calibration Additel 761A-LLP/D Series calibrators now have double the battery life of previous models, so you need not worry about the premature loss of productivity.Whether you’re working in the field or directly from the bench, our touchscreen-equipped, portable pressure calibrators have it all covered. 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-LLP/D Series,  we knew we needed to provide breakthrough improvements and add value to the existing line of calibrators  (Automatic Pressure Calibration Additel 761A-LLP/D Series).

The  Additel 761A-LLP/D Series 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!

The Additel 761A-LLP/D Series 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.

The Additel 761A-LLP/D Series 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 ranging 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.
