FLUKE 721Ex PRESSURE CALIBRATOR

The Fluke 721Ex Precision Pressure Calibrator is a high-accuracy, intrinsically safe calibrator designed mainly for gas custody transfer and flow calibration in hazardous (Zone 1) environments. 

It stands out because it has two isolated pressure sensors, allowing simultaneous static and differential pressure measurement—very useful in field instrumentation work.

As pictures, not more. Power on and working.
