Problems solved by technology

[0003] At present, although most mechanical balances can achieve high precision and a wide weighing range, they can rarely achieve the weighing of microgram-level objects, and the measurement repeatability and accuracy are not high, and the sensitivity is not high. The influence of temperature is relatively large, and some operations are more troublesome, especially for micro analysis in the laboratory, the traditional mechanical balance is particularly insufficient

Abstract

The invention discloses a simple microbalance which comprises a balance moving coil supporting part and a conversion display circuit, wherein the balance moving coil supporting part comprises a balance disc, a moving coil meter, a weighing moment arm and a balance indication arm; and the conversion display circuit comprises a moving coil current balancer, a current-to-voltage converter, an adjustable potentiometer, a digital display and a power supply. The simple microbalance disclosed by the invention has the advantages of simple structure, convenience in operation, small measurement error, high sensitivity and little ambient temperature influence, is capable of displaying the minimum weight of 0.001 microgramme, and is very suitable for microanalysis.

Description

technical field [0001] The invention relates to a balance, in particular to a simple micro balance, which belongs to the technical field of measurement. Background technique [0002] In quality metrology, the balance is an important measuring tool. It must be used to measure from the measurement of the measurement standard to the daily measurement of the value. It is not only closely related to people's daily life, but also makes a contribution to the development of science. made an indelible contribution. Until now, people are still constantly researching the balance, and with the help of modern means, various performances of the balance are improved to meet the needs of people's scientific research and daily life. However, with the development of science and the progress of society, people have higher and higher requirements for the accuracy, sensitivity and convenience of mass measurement. At the same time, people have to develop instruments suitable for various requirem...
