Frequently Asked Questions (FAQ)
The 3650 model features a 5000 psi high-pressure sensor, making it perfect for high-pressure natural gas transmission lines. It allows you to calibrate flow computers by measuring differential and static pressure simultaneously.
Yes. The "EX" designation confirms it is intrinsically safe and ATEX/IECEx certified for Zone 1. It is designed to be used in hazardous atmospheres where standard electronics are prohibited due to explosion risks.
The total shipping weight is approximately 5.0 lbs (2.3 kg). This package includes the calibrator unit, soft carrying case, batteries, test leads, and official calibration documentation.
Yes. By adding the optional Fluke 720RTD probe, you can measure temperature with 0.1°C accuracy, providing all necessary data for gas flow computer verification.
