Wagner improved the mechanism of magnetic balance which was invented by Clark, and reformed by Gast using the magnetic force. This type of balance is now manufactured and sold by Rubotherm Co. This, compared with conventional balance, has a unique advantage of transmitting the weight change indirectly to a chemical balance which is isolated from the measuring system. This mechanism makes it possible for the materials of the measuring system to have no direct contact with the weighing balance. Therefore, the weight change under even highly corrosive environment can be measured in a wide temperature and pressure range from 77 K to 2, 273 K and from high vacuum to 2, 000 bar.
