The Fluke 700PA4 Absolute Pressure Module displays pressure readings in any of 10 different pressure units you specify in the calibrator setup. The pressure module allows you to measure absolute pressure with the Fluke 740 Series Documenting Process Calibrators. The modules have one fitting and measure pressure with respect to an absolute vacuum. The pressure module measures pressure using an internal microprocessor. It receives operating power from and sends digital information to the calibrator. It features internal temperature compensation from 0 to 50 Degree Celsius for full-accuracy performance.
