Guide to Representative Sampling
Learn the many benefits of representative sampling and get answers to your representative sampling questions
The Sentry PR automatic point sampler automates sampling of free-flowing materials such as granules, powders, flakes or pellets from positive or negative pressure systems. Material characteristics are not affected by the sampler because no moving parts convey the sample material to the sample container.
To obtain a sample, the Sentry PR sampler's air cylinder moves a sample probe into the process stream. The material sampled is discharged through a flexible hose to a collection point. Material characteristics are not affected by the sampler because no moving parts convey the sample material to the sample container. Sample volume can be changed at the sampler controller.
With representative sampling, characteristics of each sample match that of the entire lot or batch—so samples are repeatable, leading to accurate sample analysis data. Automatic sampling ensures a sample can be easily and safely obtained with no need for direct human interface or interference. This ensures sample integrity as well as operator safety.
