Essentials™ Gas Sampler

Part No
Essentials™ Gas Sampler

Compact, cost-effective composite sampling for clean, dry natural gas

The Welker Essentials™ Gas Sampler is a compact natural gas composite sampler designed for accurate sampling of clean, dry single-phase natural gas. Built with Welker’s Fresh Sample System™ in compliance with API 14.1, the sampler uses a flow-through sample path to purge previous gas from the sample chamber before each actuation, helping deliver fresh, representative samples to the sample cylinder. With durable modular components, a solid stainless steel regulator, cylinder purge system, optional timer/controller, and manual test button, the Essentials™ Gas Sampler provides a low-maintenance sampling solution for remote field locations.

Where to Use
