The Fluke 750P06EX Pressure Calibrator is the industry’s first intrinsically safe, explosion-proof pressure calibrator with a built-in pump. This unique combination allows users to calibrate pressure transmitters, transducers, and gauges in hazardous areas without the need for an external pump or power source. The 750P06EX is also the most accurate and reliable pressure calibrator on the market, with an accuracy of ±0.025% of reading and a stability of ±0.01% of reading.
