Fluke 721Ex-3630 Intrinsically Safe Dual Sensor Precision Pressure Calibrator - 721EX-3630
Description
The Fluke 721Ex-3630 is an Intrinsically Safe dual sensor pressure calibrator specifically engineered for custody transfer and gas flow calibration applications. Certified to ATEX and IECEx standards, this tool allows for high-precision pressure measurement in hazardous environments (Zone 0). The 3630 model features dual isolated stainless steel sensors: a low-pressure sensor of 36 psi (2.5 bar) and a high-pressure sensor of 3000 psi (200 bar).
This rugged, handheld instrument provides 0.025% accuracy for critical measurements in the oil and gas industry. Its backlit display can show two pressure readings and temperature (via optional RTD probe) simultaneously, ensuring technicians have full visibility of gas flow parameters. The 721Ex-3630 combines laboratory-grade precision with the durability required for extreme field conditions, all while maintaining the highest safety standards.
