Additel ADT760-D [ADT760-D-02-DP100-DL] Automatic Handheld Pressure Calibrator, -12.5 to 35 psi (-0.86 to 2.5 bar) w/DP100 Sensor, HART and Data Logging, 0.02%FS, ±100 inH2O (±250 mbar). The 760-D gives you differential and gauge pressure but at a higher pressure range than the ADT760-LLP. Covering the range of -12.5 to 35 psi (-0.86 to 2.5 bar) and with an accuracy of 0.02%FS, the ADT760-D is an ideal solution to cover very common gauge and differential pressure measurements. The Additel 760-D comes with an internal module of your choice. The maximum range module compatible with the ADT760-D is to 35 psi. Lower pressure configurations down to ±10 inH2O differential can be purchased to improve accuracy at lower pressures. Documenting Process Functionality: Each model of the Additel 760 series has an option incorporating documentation and communication functions turning your 760 into a multifunction documenting process calibrator. This feature provides HART communication, task documentation and data logging.
