Sampling systems are used to safely and accurately collect representative samples of liquids, gases, or solids from industrial processes for testing and quality control. These systems are designed to ensure that samples are taken without contamination, pressure loss, or exposure to operators, maintaining both safety and product integrity. Sampling systems can be manual or automated and often include valves, probes, containers, and closed-loop mechanisms to capture the sample under actual process conditions. Proper sampling is critical for verifying product quality, ensuring regulatory compliance, detecting process issues early, and supporting reliable laboratory analysis.
