Unmatched Sample Weighing Accuracy from Outstanding Sensitivity

The GP-61KS Precision Scale from A&D Weighing has you covered for all your weighing needs. Capable of reading mass variations by its 100 mg readability, the A&D Weighing GP-61KS guarantees high performance sample weighing of particulate matter or tiny materials, obtaining reliable and close measurement values. Whether dealing with weighing tasks of chemistry applications, clinical and pharmaceutical studies, production and industrial operations, or food and textile industry, this 100 mg readability scale presents clear-cut weighing. Need a higher readability alternative? Try the Pioneer PX163 Precision Scale from Ohaus instead.

Highly Reproducible Measurement Values for Dependable Sample Weighing

Even if multi-users are managing the A&D Weighing GP-61KS, acquiring results that can be replicated is not an issue given that it presents a 200 mg repeatability. So long as similar settings are followed, the A&D Weighing GP-61KS rolls out precise measurement values throughout your weighing process. This makes it a good option for everyday weighing applications. Not only does it cut time when it comes to transcribing and re-recording weighing values each and every time, it also saves you more of it for a more comprehensivve data analysis. You can choose the GP-30KS Precision Scale from A&D Weighing if you need one with a higher repeatability value.

Functional Weighing for Laboratory, Field, and More

Weighing accuracy and precision is never a problem with the A&D Weighing GP-61KS. This unit is suited to hold substancess not exceeding a max of 61000000 g with its 384 mm pan,and is also manufactured with an internal calibration feature, allowing fast recalibration anywhere the balance is, even if relocated from a room to another. In case you need one with a higher capacity same as this A&D Weighing GP precision scale, you may want to go for .

Key Features to Take Into Account for Streamlined Weighing

Internal Calibration icon Internal Calibration

Can adapt as needed with all changes in time, temperature, movement, and stability considered, this A&D Weighing GP laboratory scale pitches highly accurate results. Listing an internal calibration feat, re-calibration is effortless even if the unit is moved regularly.

ISO compliant icon ISO Compliant

Execute a more cost-effective workflow and meet user requirements with this top loading scale that publishes ISO-compliant reports and heeds to a high quality risk-based management system.

GLP Compliant icon GLP Compliant

Do quality control measures conveniently with this A&D Weighing model because it already prints GLP-compliant reports displaying date, balance ID, time, and more to assist with your checkpoints, protocols, and record keeping.

GMP Compliant icon GMP Compliant

Following GMP protocols that hold high significance to quality management and testing, this A&D Weighing GP-61KS scale prints out reports with weighing time, results, and operator deatils to name a few. This makes it a unit to consider for food and drug manufacturing, packaging, and processing industries.

Alphanumeric LCD icon Alpha Numeric LCD

Reduce user-related errors including blunders on data readout that may just lead to inaccurate results through the A&D Weighing GP-61KS. Because it has a perfectly sized, bright, and durable Alphanumeric LCD, users enjoy vivid presentation of weighing data from any angle or point.

Savvy Multi-Device Connectivity and Communication Solutions

This GP series model does not come with a mobile application for reviewing results but it can still transfer and receive information to and from multiple devices in your lab. Communicating with laptops and personal computers is no fuss with this laboratory scale's ethernet port for wired connections.

Definitive Operational Efficiency At Your Fingertips

Have more time in your hands to do other valuable activities using the A&D Weighing GP-61KS as it brings out measurement weighing results within 1.5 seconds. It can also transfer any recorded data or results to peripheral devices in less than a minute because it is equipped with RS-232 and USB ports. There is no need to reformat reports as well since the laboratory scale already conforms to the ISO, GLP, and GMP print format.

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 WinCT

WinCT (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.
