The only similar product that we could find is made for the agriculture industry for the purpose of sampling grain products. Their unit is made of brass, conducted electricity, and is heavier and more expensive than the Filter Judge. Furthermore, their unit is not collapsible or expandable like the Filter Judge. The most important difference however was that this grain and seed sampler tended to bind up when used to sample filter media. Visit our product specs page, for more information.
The Filter Judge is a tool for taking a vertical core sample of media (sand, anthracite, garnet, etc.) from a filter in a water treatment faciltiy.
