PM series balances are equipped with an innovative measuring system based on RADWAG MonoBLOCK? technology. Use of the new measuring system, which is a subject matter of RADWAG patent, guarantees stability of repeatability over time at a range sd<1d. The unique measuring system solution is characterized with great resistance to ambient conditions change. An in-built 4-point protection system prevents balance overloading, this ensures safety in case too heavy load is applied onto the weighing pan.
