Laboratory balance calibration weight set 1mg-2kg stainless steel weight

Standard weights are physical measuring tools that can reproduce mass values, with certain physical characteristics and features. Standard weights are clearly classified into grades, and the weight grades are divided into9One:E1LevelE2LevelF1LevelF2LevelM1LevelM12LevelM2LevelM23LevelM3Grade. The so-called equality refers to the uncertainty of the weight, with a correction value; Grade is the indication value error, without correction value, the indication error of the weight is qualified if it is within the allowable range. In modern quality, weights are standard measuring tools for transmitting mass values. The quality value is based on the preserved kilogram prototype of platinum iridium alloy. Each country divides weights into national kilogram standards, national kilogram sub standards, kilogram working standards, as well as working standard groups composed of multiples and components of kilograms and various working standard weights.

Precautions for using stainless steel weights:

1Before using the weight, use a cleaning brush and wiping cloth to remove dust and other stains from the surface of the weight.

2It is strictly prohibited to touch weights directly with hands. When using weights, please wear gloves and use tools to pick up the weights. (Please refer to the "Weight Attachment" for gloves and tools)

3Before conducting balance testing or weight comparison, the weights need to be kept at a constant temperature to achieve the atmospheric conditions of the laboratory, otherwise it will affect the test results.

4After use, the weights must be stored in the original packaging box.

Standard weights are mainly used for verifying and calibrating weights,So do you know why standard weights need to be calibrated regularly?

Weights as a calibration standard for electronic scales and scales,Deciding whether the quality of electronic scales and scales meets the standards,Sometimes weights of different materials may be stored in improper locations,Corrosion caused by certain irritants, as well as air and temperature factors,Generate a series of errors,Therefore, regular calibration of the weights is required,To ensure the accuracy of the nominal value of the weights.The use of converted mass values for the mass value of weights is a significant improvement in quality,No need to perform air buoyancy correction on weights made of different materials anymore,Therefore, simplifying the process of weight verification,It also eliminates the error caused by measuring the same object with weights made of different materials.Weights are a reflection of the unit of mass,Having a certain quality,Used to measure the mass of an object,And firmly establish various scales and apparatus,Therefore, regular calibration is required.
