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-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.
