What is the difference between Weight & Mass?
Weight is often taken to mean the same as mass, however, there is a difference, which for calibration purposes is important to note: Mass is the measurement of the amount of material that makes up the object. Weight is the gravitational force acting on the object.
Why Calibrate?
Accuracy is key as weights are used to calibrate scales and other weighing equipment, an inaccurate weight, in turn, will have a knock-on effect and will produce inaccurate scale calibration. A calibrated set of weights allow the scale error of the balance to be assessed and corrected to the highest accuracy. Calibration weights are available in a wide range of classes and specifically used for certain types of balances such as:
- M1 calibration weights are used for testing and calibrating standard scales
- F1 calibration weights are used for testing and calibrating precision electronic balances
- E2 calibration weights are used for testing and calibrating analytical balances
