比重天平

模型HV-RTE001
比重天平提供了一种简单快速的方法，可以直接读取橡胶和其他弹性体的比重。从而减少劳动和消除计算。找出样品的比重只需要大约半分钟。该天平由一个刚性秤组成，比重(SG)印在一个沉重的底座上。在天平的中心点，通过宝石轴承最大限度地减少摩擦，一个平衡臂被旋转。在臂的一端，两个不锈钢针挂着纱线。其中一个别针与玻璃罐固定在底座上。在使用过程中设有保护装置，以避免玻璃瓶意外掉落。在平衡臂的另一端，固定有指示被测材料比重的指针。还提供了滑动砝码，用于不同砝码样品的初始平衡和底板的调平。 Two models of balance, one with range of specific gravity between 0.9 to 3.0’’ the second with range of specific gravity / between 0.2to2.0 are available. A sample of any shape weighing between 5 and 12g can be tested in the first modal, that weighing between 3 and 5g can be tested in the second model, and that weighing between 1and 2g can be tested in the third made. In case of second and third model, the lower pin is quite heavy and also acts as sinker. Also in these models the glass jar is kept on the base of a frame, which can be slided up and down on a rod fixed to the base plate to cover the full range at specific gravity.
