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-500
The Additel 761A-500 will generate and control from vacuum pressures up to 500 psig (35 bar.g). Both gauge and absolute pressures can be realized due to a built-in barometer. Each unit comes with a CP500 module (-12.5 to 500 psig) for the high range and the low range can be preconfigured based on the variety of modules available down to 10 psig (0.7 bar.g).

ADT761A-1K
The Additel 761A-1K will quickly generate and control from vacuum pressures up to 1,000 psig (70 bar.g).  Like the ADT761A-500, both gauge and absolute pressures can be realized due to a built-in barometer. Each unit comes with a CP1K module (-12.5 to 1,000 psig) for the high range and the low range can be preconfigured based on the variety of modules available down to 30 psig (2 bar.g).
