The Additel ADT760-D-DP20-DL Automatic Handheld Pressure Calibrator with DP20 Sensor, HART and Data Logging, ±20 in (±50 mbar) is a portable automated pressure calibrator in the palm of your hand. Weighing less than 4 lbs (1.8 kg), the []'s innovative design contains a built-in pump, precision pressure sensor, internal controller and a large touch-screen color display. To generate pressure, simply key in the desired pressure and the ADT760-D-DP20-DL will do the rest. Each unit has four channels: one internal pressure channel for source and measure pressures, two external pressure measurement channels, and one electronic measure and source channel.

The ADT760-D-DP20-DL 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-DP20-DL is an ideal solution to cover very common gauge and differential pressure measurements. The Additel ADT760-D-DP20-DL comes with an internal module of your choice. The maximum range module compatible with the ADT760-D-DP20-DL is to 35 psi. Lower pressure configurations down to ±10 inH2O differential can be purchased to improve accuracy at lower pressures.
