Für dieses Produkt gibt es zur Zeit nur eine englische  Produktbeschreibung:

The GOLD BOTTLE is used to verify the operational repeatability of torque testing instrumnets.
This device is constructed with high energy permanent magnets and is pre-set at the factory to a customer specified torque value of between 5 to 15 inch pounds (inlbs).
Each GOLD BOTTLE is labeled with its exact torque rating and repeats to an accuracy of +/- 0.2 inch pounds (inlbs).

Since the cap torque of this bottle is the torque produced by the permanent magnets, the value will always be the same.
Therefore, when tested on the torque tester, the measured value willalways be the same unless something has changed within the torque testing instrument itself.
The user is able to quickly check the torque tester without having togo through the calibration procedure.

The GOLD BOTTLE is provided with a 28mm to 43mm cap to match the chustomer's chuck.
Steinfurth can also provide the bottle with any customer supplied cap at a nominal additional cost.
