What are the mandatory verification items in measurement?

Settlement refers to the measuring instrument involved in the quantity used in the process of settlement basis. Such as: electronic balances used to weigh gold and silver in gold and silver trading transactions, electronic scales used to weigh seafood in seafood markets, electricity meters and water meters used in every household, filling machines for quantitative packaging, balances, etc., such as rice, oil, shower gel, shampoo, etc., can be seen everywhere in life!

As for your company's instruments, which are the compulsory inspection measuring instruments, you can check the compulsory inspection table. But give a suggestion: the measurement law stipulates that even if it is not a compulsory inspection of measuring instruments, it must be verified or calibrated according to law, and your company has not passed the measurement standard or CANS assessment, it is still impossible to self-test, and it is still necessary to find the relevant measurement agency to verify or calibrate, these money can not be saved, or to ensure reliable quality and can maintain effective operation of the most important!

Withstand voltage tester, electronic scale, caliper, tensile force meter, image tester, reliability testing machine, micrometer, temperature and humidity meter, digital thermometer, oven, milliohm meter, microscope belongs to the strong inspection equipment must be verified, reflow soldering machine, LCR tester, overlapping current source, network analyzer, RoHS tester to see the use, generally also need to be measured and verified before it can be used, magnifying glass, air compressor can be used as a tool can not be verified.

According to the above-mentioned requirements: the withstand voltage tester must be a strong inspection measuring instrument, and the electronic scale must be used for ** settlement. LCR testers, overlapping current sources, network analyzers, RoHS testers, image testers, air compressors, reliability testing machines, reflow soldering machines, microscopes, magnifying glasses, and ovens do not belong to the measuring instruments managed by the state according to law.
