Abstract

The invention discloses an electronic analytical balance. The electronic analytical balance comprises a base, wherein a weighing platform is arranged above the base; a weighing sensor is arranged between the base and the weighing platform; the base is provided with an operation panel; a sealed cover made of PCB (Printed Circuit Board) is covered above the weighing platform; the electrostatic interference can be effectively prevented by setting the sealed cover of the PCB board, so that the weighing precision is improved.

Description

technical field [0001] The invention relates to an electronic analytical balance. Background technique [0002] At present, when the electronic balance weighs items, some items are electrostatically charged, which will interfere with the weighing sensor of the electronic balance, thereby affecting the accuracy. Contents of the invention [0003] The purpose of the present invention is to overcome the defects existing in the prior art, and provide an electronic analytical balance, which can shield the electronic balance from items that generate static electricity. [0004] In order to achieve the above object, the technical solution of the present invention is to provide an electronic analytical balance, including a base, a weighing platform is arranged above the base, and a weighing sensor is arranged between the base and the weighing platform , the base is provided with an operation panel, and the upper cover of the weighing platform is provided with a closed cover ...
