The Sample Master^™ 403 Cylinder Manifold minimizes the opportunity for condensation, and drastically simplifies sampling. The 1/16" inside diameter passage way of the manifold fitting allows for quick purging without liquid accumulation in the sample flow path. A pressure gauge and purge valve are assembled to the manifold at the factory; eliminating tubing and fittings between hardware components, reducing purge volume and emissions, and significantly reducing the cost of ancillary hardware purchase and set up time. To prepare for sampling, simply connect the manifold to the source valve and sample cylinder.
