The Fluke 700P00 Differential Pressure Module (1 in. H2O) has been discontinued, it has been replaced by the Fluke 750P00 Pressure Module
The Fluke 700P00 Differential 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 pressure with the Fluke 700 Series Process Calibrators. This differential pressure module has two pressure fittings and measures the difference between the applied pressure on the high fitting versus the low fitting. It functions like a gage module when the low fitting is open. The pressure module measures pressure using an internal microprocessor.
