Additel ADT 761A-1K [ADT761A-1K-02-CP50-N] Automated Pressure Calibrator, -13 to 1000 psig (-0.90 to 70 barg) w/ Internal Module -13.5 to 50 psig (-0.95 to 3.5 bar) and 1/4 NPT Female. The Additel ADT761A-1K-CP50-N Automated Pressure Calibrator with CP1K and CP30 Sensors, -0.9 bar to 70 bar.g (-13 psi to 1,000 psig), 1/4 NPT (F) is completely self-contained and automated with a built-in pump for pressure generation and precision control technology. With removable internal pressure modules, 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 - simply set the desired pressure and watch the calibrator do the work. The Additel ADT761A-1K-CP50-N will generate and control from vacuum pressures up to 1,000 psig (70 bar.g). This unit can typically achieve 1,000 psi in less than 45 seconds. Both gauge and absolute pressures can be realized due to a built-in barometer. Each unit comes with a CP1K module (-13 to 1,000 psig) for the high range and the low range module, CP50  -13.5 to 50 psig (-0.95 to 3.5 bar).
