Applications/Examples of results
You can use it to check the contents of a stainless steel container. The integrated viewing window has the frame and glass fixed together, so the glass will not fall off. It prevents damage from accidentally dropping the glass, injuries from shards, and contamination from foreign objects. It has a Hurel connection, so it can be easily attached if there is Hurel piping on the container lid. We also accept custom orders for production in your desired size.
