Overview

The Fluke 721 Precision Pressure Calibrator is the ideal tool for gas custody transfer applications. It can be configured by selecting either a 16 psi (1.1 bar) or 36 psi (2.48 bar) low pressure sensor then adding any of seven high pressure ranges: 100, 300, 500, 1000, 1500, 3000 or 5000 psi (6.9, 20, 24.5, 69, 103.4, 200, 345 bar).
