Often large metal parts require Brinell testing to confirm the hardness of the metal and these large parts can prove to be a significant challenge when testing the hardness of metal. A large part by its very nature is difficult to reach and difficult to test. Portable testers can be very helpful in testing large parts because they provide the flexibility to be able to test the part where it is located instead of having to move the part to the location of the tester. However, some large parts can be difficult to test even with the use of portable testers. Quite often this is a result of the accessibility of the test location.

Large parts might include pipes where the desired test location is not readily accessible from the edge of the pipe. Large castings may also require testing in locations which cannot be accessed when using the standard base.

To address this challenge, King Tester has developed specialized basis to allow the tester to be used to test in the desired location. One of the special bases which is particularly versatile we refer to as the “King Chain Adapter” or a “King CA base”. This special base allows the flexibility to move the test head into the base which can then be easily adapted through the use of a chain to test a large part at the desired location.

There is no practical limitation to the length of chain which can be used and therefore with the King chain adapter base the King portable Brinell hardness tester is easily adapted to be able to test even the largest parts in locations as desired.

The King Tester head used with the King Tester Chain Adapter base allows the user to place a full load (up to 3000 kg force) onto the large part in the desired testing location and there are no compromises in the accuracy or precision of the results from the King tester had when used in conjunction with the King tester chain adapter base.

You can be certain when you use the King Portable Brinell hardness tester in conjunction with the King Chain Adapter Base that you are conducting a test which fully conforms with ASTM standards.
