Single Container Water Hammer Tester
In order to supply safe glass containers to the market, Toyo Glass runs a wide variety of strength tests. This Single Container Water Hammer Tester makes it possible to measure water hammer strength comfortably and accurately.
 Features 
The test can be conducted with a single glass bottle without a carton.
Single Container Water Hammer Tester measures water hammer strength of a glass bottle by dangling a bottle at its neck and then dropping a weight on the top of the filled and capped bottle from above to generate Water Hammer Phenomenon. As no carton is required, the test can be conducted using only a single glass bottle, and due to that, the strength of a glass bottle itself can be examined.
