Economical OIML Class M1 Hexagon-shaped Cast Iron Test Weights China Manufacturer 100g 200g 500g 1kg 2kg Hexagon Weights
Cast 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. ‌Field standards for testing industrial devicesClass III, Class IIIL or Class IIIITesting for non-marked scales withoutClass designationVerifying scales are within specified accuracy and tolerance

E1 E2 F1 F2 M1 OIML Standard 1mg-2kg 5kg 10kg 20kg  Low Magnetic Stainless Steel Counterpoise Calibration Weights Set
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.
