Industrial Balance with Performance and Accuracy

The GP Series incorporates our enhanced weighing sensor, the Double Leveraged Super Hybrid Sensor(SHS). 

Building on the basic SHS features of speed and stabilization, our enhanced SHS technology brings the most accurate weighing results to industrial balances in the 12kg to 101kg capacities class.

Saves Time and Money with Internal Calibration

The GP internal calibration with an internal mass saves time and money. 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.

Prevent Mistakes with Large, Clear VFD

  • Wide angle view is easy to see from anywhere in the room
  • Easy to see, even in the dark - bright light with high contrast
  • Fewer errors due to hard to read screens
