Fluke 721Ex-1603 Intrinsically Safe Dual Sensor Precision Pressure Calibrator - 721EX-1603
Description
The Fluke 721Ex-1603 is an Intrinsically Safe dual sensor pressure calibrator specifically designed for gas custody transfer applications. Certified for use in explosive gas environments (ATEX/IECEx), it allows technicians to perform high-precision calibration in hazardous areas without compromising safety. Featuring two isolated stainless steel pressure sensors, it simultaneously measures low and high pressure with a single, rugged handheld tool.
The 1603 model is equipped with a low-pressure sensor of 16 psi (1.1 bar) and a high-pressure sensor of 300 psi (20 bar). This configuration makes it ideal for gas flow computer calibration and general pressure maintenance. Its large backlit display shows both pressure readings and temperature simultaneously, while the Pt100 RTD input allows for even greater accuracy in calculating gas flow corrections.
