Industrial samplers are used to extract samples of free-flowing materials such as coal, aggregate, wood chips, plastics and liquid. The design and operation of the sampler eliminates issues inherent with hand sampling methods and provides a representative and repeatable sample. Intersystems designs and manufactures rugged industrial sampling systems for a variety of applications. Intersystems samplers can be used in gravity, pneumatic or liquid lines and can be installed in chutes and at the end and middle of moving belts. Automatic samplers come complete with controls and accessories such as collection carousels and PLC interface capability are available.
