Test Weights

W&J China Calibration Weights manufacturers - W&J,Good product quality, reasonable price and high cost performanceWe provide standard weights such as cast iron weights and stainless steel weights. It can also be customized according to customer needs. All weights comply with OIML international standards. It is suitable for laboratory testing, measurement testing institutions, pharmaceutical factories, food industry, environmental testing, etc.Classification of calibration weightsAccording to different standards and uses, calibration weights can be divided into different types:a. Classification by material: mainly including weights made of iron, stainless steel, aluminum, copper and other materials.b. Classification by accuracy: such as E1, E2, F1, F2, etc., where E1 is the highest accuracy level.c. Classification by shape: such as disc type, cylindrical type, rod type, etc.

Definition and function of weightsA calibration weight is a precisely manufactured mass block used to provide a standard mass or load during the measurement process. Its main applications include:a. Calibration of measuring equipment: such as balances, electronic scales, etc., to ensure that the readings they display are accurate.b. Calibration of other equipment: such as certain mechanical equipment, used to determine the load or other parameters of the machine.c. Providing standards for scientific research: In some experiments, accurate mass is required as a reference, and weights come in handy.

OIML and ASTM StandardCast ironCast iron weights are a measuring tool that measures the weight of an object by comparing its mass. It is done by placing a weight on the balance pan while weighing the weight of another object. Cast iron weights usually have precise weight values because they are calibrated on a precision balance. When the balance weighs an object, the weight exerts a certain force on the balance, which in turn affects the balance point of the lever, thereby achieving accurate measurement of the mass of the object. ‌

The main material of the steel chrome-plated weight is 45# steel with chrome-plated surface. The internal material is 45# steel, and the surface is processed by special grinding and electroplating technology, which has high corrosion resistance and wear resistance.
