To meet the requirements of evolving pressure calibration standards and reference class accuracy pressure instrumentation, Fluke Corp. introduces the 750P Series Pressure Modules. The 48 precision modules enable gage, differential, dual range, absolute, and vacuum pressure measurement with Fluke 750 and 740 series Documenting Process Calibrators and 725, 726 Multifunction Process Calibrators. The 750P Series is designed for the different use models specified in new calibration requirements. The new modules cover pressure calibrations from 0 to 1 in H20 to 10000 psi (2.5 mBar to 690 bar) with a 0.025 percent reference uncertainty. Digital communication to calibrators eliminates errors due to poor connections and electrical interference. For applications in pharmaceuticals or custody transfers in oil and gas, there are 11 new modules with two-times more accuracy than standard modules. For industries like nuclear and pharmaceutical that now require calibration every six months, the 750P Series offer a six month specification that provides better accuracies between these shortened calibration cycles.
