Consider the Ecom 721Ex Intrinsically Safe Calibrator, which is ATEX Zone 1 and IECEx certified. This is a precision pressure calibrator with two independent pressure sensors. It is ideal for gas custody transfer applications due to its simultaneous static and differential pressure measurement.
Additionally, this calibrator can be configured by selecting low-pressure sensors at 16 PSI (1.1 bar) or 36 PSI (2.48 bar) and then adding one of seven high-pressure ranges (6.9, 20, 24.5, 69, 103.4, 200, 345 bar). This feature is not available on comparable devices. You can alternate between two isolated stainless steel pressure sensors for testing.
The purpose of Ecom instruments is to ensure safety in an environment where mistakes are never forgiven. Their instruments are always completely safe to operate. They are widely regarded as a pioneer in the field of mobile explosion protection. They constantly set new standards and create new opportunities by utilizing German engineering, skills, and patents.
