A patented shock absorber beneath the pan helps protect the sensor from disturbances. The compact weighing module can be integrated with a wall- or panel-mounted display, a slim 80 mm configuration, custom weighing pans, or vacuum chamber weighing systems. These capabilities support precise sample measurement in molecular biology, bioprocessing, formulation, and other research and manufacturing applications.
