This 100g calibration weight is used to calibrate 100g [max] electronic scales and can be used to calibrate manual scales as well. This can be used for calibrating all the scales we sell in the Accessories section of our website. Directions for how to use a cal-weight come with every scale. It's simple and fast. If you want your scale to be as accurate as possible, from time to time we must test the scales with a cal-weight and calibrate when necessary. All the scales we sell are professionally calibrated prior to shipping to you.
