No autographs, please. The unrivaled accuracy of Welker’s GSS-4PM Gas Sampling System is world-famous. Its unparalleled decades-long history of representative sampling, repeatability, and accuracy have made the GSS-4PM the composite sampling system for natural gas—wet or dry, clean or dirty.
Probe-mounted and self-purging, the GSS-4PM is a self-contained system compatible with single cavity and constant pressure cylinders. With the Vanishing Chamber™ collection cup at the heart of the positive displacement pump, there’s no doubt your samples will be as representative and accurate as the results of an online analyzer.
