Problems solved by technology
[0003] There are certain defects in the prior art tray balances used by students for chemical experiments: chemical tray balances are mostly used for weighing chemicals, and the accuracy of weighing is required to be high. Adjust to a balanced state, but the position where the tray balance base is placed may have a certain inclination angle, resulting in deviations during weighing, affecting the results of the experiment, and reducing the reliability of the experimental data

The invention discloses a chemical experiment counter balance for students, which comprises counter balance weighing assemblies, a base assembly, balance support adjusting assemblies, a first balanceadjustment reference assembly and second balance adjustment reference assemblies, wherein the counter balance weighing assemblies are arranged on the base assembly, the balance support adjusting assemblies are respectively arranged at two side corners of the base assembly, the front surface of the base assembly is embedded with the first balance adjustment reference assembly, and two side edges ofthe base assembly are respectively embedded with the second balance adjustment reference assemblies. The beneficial effects are that the chemical experiment counter balance for students can ensure the balance of the placement position of a base, and the base is adjusted to be balanced through the balance support adjusting assemblies and the balance adjustment reference assemblies, thereby effectively avoiding a problem that an error occurs in weighing due to inclination of the base, ensuring the accuracy of a weighing result, and thus ensuring the accuracy and reliability of an experiment result to be higher.
Description
technical field [0001] The invention belongs to the technical field of student experiment equipment, and in particular relates to a chemical experiment pallet balance for students. Background technique [0002] Chemical balance is a precision mass measuring instrument used in chemical experiment research, and is one of the commonly used weighing instruments in chemical laboratories. Generally used to measure the quality of chemicals. A traditional chemical balance consists of a balance and a weight: a balance is a measuring instrument made according to the principle of a lever; the weight is a standard of quality. Mass and weight are two different concepts in physics, but due to historical and customary reasons, both mass and weight use the same unit, which confuses the use of the two. It is customary to use the term "weight" in chemistry, but to be precise, the result of weighing in a balance is the mass value of an object. [0003] There are certain defects in the prior...
