The 721 dual-range, pressure calibrator with dual isolated pressure sensors can take simultaneous static and differential pressure measurements in a single tool for gas custody and transfer applications. It can be configured by selecting either a 16-psi or 36-psi low-pressure sensor, and then adding any of seven high-pressure ranges, including 100, 300, 500, 1,000, 1,500, 3,000 or 5,000 psi.
