The dead-weight testers BA2 and BH2 are designed to calibrate pressure monitoring systems. They consist of a pressure generator, a piston cylinder unit including a given "A" section and a set of weights with an accurate given value "m" which allow the establishment of the relation p = (m x g)/A. Thus, they comply with the units of the International System (SI).

The dead-weight testers BA2 and BH2 are sturdy and easy to operate. Moreover they have an excellent long-term stability providing a high metrological property.
