AND GP Series Industrial Balance



Kitoma Indonesia : AND GP Series Industrial Balance

The AND 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 result to industrial bbalances in the 12kg to 101kg capacities class.


Item Available

GP-S with detached display unit

GP-30KS   : (31kg/0.1g)
GP-32KS   : (61kg/0.1g* . 31kg/1g)
GP-60KS   : (61kg/1g)
GP-61KS   : (61kg/0.1g)
GP-101KS : (101kg/1g)


The GP-32K/KS and GP102K have both presicision and standard ranges. The precision range has a higher resolution and the standard one has a normal resolution. Pressing the RE-ZERO key allows weighing in the precision range, regardless of the tare value. The SmartRange function enables you to weigh or add samples in the precision range without removing the container and/or those objects that have been placed on the pan.

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.

Automaticaly 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 our 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 pan. The adjusted weighing accuracy is within ±15 digits in relation to the weighing capacity while conforming to the OIML's Class II balances definitions after using GP's internal calibration mass.

Standard WinCT

WinCT (Windows Communication Tools SOftware), provides easy transmission of weighing data from A&D balances to a computer using the RS-232C interface. Speed of data transfer into Windows applications in a manageable format is limited only by the computer's capabilities.

RS-232C Interface

Using a USB/RS-232C Converter, you can transfer data between a USB-equipped PC and a GP balance. This also makes your GP balance hot-swappable meaning that there is no need to turn the balance and/or computer off before disconnecting the balance.

GLP/GMP/ISO COmpliance

Allows GLP, GMP and ISO balance management by outputting the Balance ID number and data used to calibrate the balance. The data can be output to A&D's AD-8121B printer or a PC, indicating date, time, Balance ID number, serial number and calibration data.

can be set by pressing the MODE key and response speed can be adjusted to FAST, MID or SLOW

Standard Comparator Function

Offsers increased flexibility and compatibility for a vast number of applications. You can input a target weight and weigh heavier or lighter items using either the keyboard or by placing samples on the pan. HI, OK or LO will be indicated on the display to show the comparison results.

Automatic Counting Accuracy Improvement (ACAI)

Is a novel and useful approach to ensuring the utmost in performance when counting even the smallest of items. ACAI automatically updates and refines the average piece weight used to determine the total quantity.

Percentage Function

Facilitates an effective and quick comparison of a sample or commodity against a known reference mass.
Simply place an object on the pan to register its weight as 100%. Place another object on the pan to compare its weight in percentage mode.

Overall Capacity Indication

Is a unique and helpful feature. By indicating how much of the balance's capacity has been filled, the risk of overloading the balance is minimized.
