External calibration requires a great deal of skill, time and an expensive external mass. With our internal calibration with internal mass, the balance is calibrated very quickly. Automatic Self Calibration — Self-calibrates automatically when the balance detects ambient temperature changes. One Touch Automatic Calibration — Allows you to calibrate the balance on demand with just the push of a button. Calibration is essential for accuracy in weighing. For example, in high resolution balances, changes in sensitivity drift can be caused by changes in the ambient temperature. Take the GP-30K for example, the weight might change by 0.9g with a change of 10°C (Sample’s weight: 30kg). Thanks to Double Leveraged Super Hybrid Sensor, the GP’s motor-driven internal calibration mass is equivalent to a 50kg calibration mass in terms of top loading capacity on the weighing pans
