Fluke 721Ex-3650 Intrinsically Safe Dual Sensor Precision Pressure Calibrator - 721EX-3650
Description
The Fluke 721Ex-3650 is an Intrinsically Safe dual sensor pressure calibrator engineered for custody transfer and gas flow calibration in hazardous environments. Certified to ATEX and IECEx standards, this tool allows for precise measurement of both low and high pressure simultaneously. The 3650 model features a low-pressure sensor of 36 psi (2.5 bar) and a high-pressure sensor reaching up to 5000 psi (345 bar), making it the ideal standard for testing high-pressure gas systems.
This rugged, handheld instrument is designed for the most demanding oil and gas applications. With isolated stainless steel sensors, it provides 0.025% accuracy for critical measurements. Its backlit display shows two pressure readings and temperature (via optional RTD probe) simultaneously, ensuring technicians have all necessary data at a glance. The 721Ex-3650 combines safety, durability, and laboratory-grade precision in one portable package.
