This product is developed and produced by DahoMeter, using the Archimedes principle buoyancy method and software technology to automatically calculate the mass change rate or volume change rate,It has the characteristics of good measurement repeatability, high accuracy, and simple operation.

The volume and mass change rate refers to the volume change that occurs when a product is immersed in a liquid medium for a certain period of time or in a saturated state. The ratio of the difference in weight before and after immersion to the weight before immersion is called the mass change rate; The ratio of the difference in volume before and after immersion to the volume before immersion is called the volume change rate; It is one of the intrinsic constants of sealing rubber.
