High Accuracy Weighing Established from Superior Sensitivity

Perfect for meeting weighing requirements of clinical and pharmaceutical labs, universities, and food manufacturing facilities to name a few, the GP-20K Precision Scale from A&D Weighing helps you confidently weigh minute samples including particulate matter. Since it discerns mass variations through its 100 mg readability, the A&D Weighing GP-20K precision scale puts your budget to an good advantage while presenting the most accurate weighing performance for your industrial applications, manufacturing operations, or daily laboratory tasks,. Not what you exactly need? The GP-30KS Precision Scale from A&D Weighing also offers the same 100 mg readability. You might want to consider it instead. For a unit with a higher sensitivity, try the Explorer EX4202 Precision Scale from Ohaus.

Ultimate Reproducibility for Reliable Sample Weighing

A high quality unit like the GP-20K Precision Scale from A&D Weighing that comes with a 100 mg repeatability brings about reproducible results recommended for everyday weighing applications. Even with multiple users, the A&D Weighing GP-20K generates high precision weighing just as long as similar weighing conditions are implemented. Because it presents almost unvarying measurement values, this model saves you time when it comes to re-recording data, re-alloting it to analyzing results instead. Interested in a higher repeatability unit? Some replacements you may want to evaluate include the Explorer EX423 Precision Scale from Ohaus.

Multi-Purpose Sample Weighing for Lab, Field, and More

Whether doing tasks out in the field or inside a lab, the A&D Weighing GP-20K racks up accurate and precise weighing each and everytime through its internal calibration feat, self-calibrating even when it's transferred from one room to another. Designed with a 384 mm weighing pan, this precision scale can accommodate up to a max of 21000 g of samples so make it to a point that your load do not exceed this. A great option for a higher capacity unit would be the GP-32KS Precision Scale from A&D Weighing.A different model but with the same capacity as this unit that you can pick is the WLC 21.X2 Precision Balance from Radwag.

Key Features to Consider for Easier Weighing

Internal Calibration icon Internal Calibration

This A&D Weighing GP precision scale has an internal calibration feat, adjusting as needed to consider variance in movement, temperature, time, and stability. This supports weighing precision and accuracy even if the unit is relocated daily.

GLP Compliant icon GLP Compliant

Sending back GLP compliant reports, this A&D Weighing precision model allows you to track tasks of your research or experiment with no fuss. Cut out time formatting reports with this unit, having these following requirements of GLP, complete with date, time, balance ID, and other relevant data recommended for quality control purposes.

GMP Compliant icon GMP Compliant

Present reports complete with operator details, results, and weighing time plus more with this A&D Weighing GP-20K top loading scale to conform to GMP regulations. This model is perfect for use in manufacturing, testing, quality assurance of various products including raw materials, goods, food, and drugs.

Alphanumeric LCD icon Alpha Numeric LCD

Clear visibility of measurement data is ensured by the A&D Weighing GP-20K featuring a long-lasting Alphanumeric LCD. Because misreading weighing values are avoided, even if they are workng inside rooms with not the best lighting conditions, getting improved operational efficiency is no-sweat.

Smart Device to Device Connectivity and Communication Solutions

An advice when purchasing a precision scale is to find out the connectivity solutions it can offer. Improve your work by correctly transferring measurement results with this A&D Weighing GP-20K's an ethernet port for a wired connection.

Proven Operational Efficiency At Your Fingertips

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.

■ 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 Win

CTWinCT (Windows Communication Tools Software), provides easy transmission of weighing data from A&Dbalances 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.
