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.

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).

ADT761A-BP

The Additel 761A-BP is designed for calibration of barometer sensors. With a range of 100 to 1200 hPa and an accuracy of 0.01%FS, this unit is ideal for calibration on the bench or in the field.
