Additel ADT761A-500 [ADT761A-500-02-CP200-N2] Automated Gauge / Absolute Pressure Calibrator, -13 to 500 psig (-0.9 to 35 barg) w/ Internal Module -13.5 to 200 psig (-0.95 to 14 bar) 0.02%FS  and 1/2 NPT Female. The Additel ADT761A-500-CP200-N Automated Pressure Calibrator with CP500 and CP100 Sensors, -0.9 bar to 35 bar.g (-13 psi to 500 psig), 1/2 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-500-CP200-N 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 (-13 to 500 psig) for the high range and the low range module, CP200 Module -13.5 to 200 psig (-0.95 to 14 bar) 0.02%FS  and 1/4 NPT Female.
