Fluke Corporation has broadened its suite of precision pressure calibration products with the addition of two new models of pressure calibrators: the 719Pro and 721 Dual Range Pressure Calibrator. The 719Pro Electric Pressure Calibrator is a tool for calibrating high accuracy transmitters, pressure switches and pressure gauges. It features high accuracy pressure measurements and an onboard electric pressure pump that can generate up to 300 psi (20 bar). It also measures, simulates and sources 4-20 mA loop current signals and can measure up to 30 V dc. Its internal 24 loop power supply can power a transmitter under test. The 721 Dual Range Pressure Calibrator with dual isolated pressure sensors allows technicians to 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 (1.1 bar) or 36 psi (2.48 bar) low pressure sensor and then add any of seven high pressure ranges including 100, 300, 500, 1000, 1500, 3000 or 5000 psi (6.9, 20, 24.5, 69, 103.4, 200, 345 bar).
