Superior Sensitivity for High Accuracy Weighing

The GP-30K Precision Scale from A&D Weighing presents highly accurate weighing of particulate matter or other small samples thanks to its 100 mg readability. Robust and engineered for use not just in laboratories but also even for universities, industrial facilities, or production houses, the A&D Weighing GP-30K shows close measurement values, assuring high performance weighing for quality control processes, laboratory tasks, as well as manufacturing purposes. Another option with the same 100 mg sensitivity that you can consider is the the GP-61K Precision Scale from A&D Weighing from the same GP series. However, if you want a unit with a higher division size, you might want to try the Scout STX222 Portable Balance from Ohaus.

Complete Reproducibility for Valid Mass Weighing

When it comes to obtaining results that can be duplicated for your applications done on a day-to-day basis, you can trust the GP-30K Precision Scale from A&D Weighing that offers 100 mg repeatability. Even with multi-users managing the A&D Weighing GP-30K, the unit yields highly precise weighing measurement values throughout your complete weighing process for credible results, being that similar settings are followed. If you need higher repeatability from the same manufacturer or another industry celebrated brand, go for the Scout STX2202 Portable Balance from Ohaus

Multipurpose Weighing from Laboratory to Field

Before procuring a precision balance, make sure you review the sample loads you will be weighing at present and in the future. These should be within the capacity range of the unit and won't go over its weighing pan. With the A&D Weighing GP-30K, you can work on light or heavy substances whether solids or liquids, provided that these do not go over 31000 g and its 384 mm weighing pan. Weighing accuracy and precision will never be a problem as the balance features internal calibration, allowing quick self calibration as needed. You can settle with The GP-61K Precision Scale from A&D Weighing or the HY10.32.HRP.H High Resolution Scale from Radwag if you are experimenting on heftier samples but still require the same readability as the A&D Weighing GP-30K. But if you need something similar to this GP series unit but of a different model or from another well-trusted manufacturer, check out the GP-32KS Precision Scale from A&D Weighing instead

Complete with Instrumental Features

Internal Calibration icon Internal Calibration

This A&D Weighing GP precision scale comes with an internal calibration feature, adjusting as needed to consider changes in temperature, time, stability, and movement. This confirms weighing accuracy and precision even if the unit is relocated regularly.

ISO compliant icon ISO Compliant

Get a more structured workflow right at your hands and meet user requirements with this scale , adhering to a high quality risk-based management system and printing out reports compliant to ISO.

GLP Compliant icon GLP Compliant

Following the requirements set by GLP, this A&D Weighing precision model renders reports complete withc date, time, balance ID, and more. This means it is more convenient to track activities of your experiment or research especially for record keeping and quality purposes.

GMP Compliant icon GMP Compliant

Delivering reports compliant to GMP, the GP-30K Precision Scale from A&D Weighing offers reports with weighing time, results, and operator deatils included. This makes it a recommended top loading scale for doing quality control and testing on manufactured food, drugs, raw materials, and goods.

Alphanumeric LCD icon Alpha Numeric LCD

Clear visibility of weighing measurements is ensured by the A&D Weighing GP-30K featuring a durable Alphanumeric LCD screen. Because users then avoid misreading weighing values, even if they are inside facilities with not the best lighting conditions, attaining improved operational efficiency is no-sweat.

Coverall Multi-Device Connectivity Solutions

This GP series model doesn'thave a mobile app for recovering results with a few clicks but it can still be linked to multiple devices in your workroom. Communicating with PCs and laptops is easy-breezy with this lab scale's ethernet port for a wired connection.

Unequivocal Operational Efficiency

Free up more time and re-allot this to high priority tasks using the GP-30K Precision Scale from A&D Weighing. Endorsing operational efficiency by rolling out measurement weighing results in just 1.5 seconds, this A&D Weighing GP precision balance is a key to achieving amplified laboratory weighing output and fine-tuning lab procedures. Transferring weighing records to peripheral devices will never be a problem as the model has an available RS-232 and USB ports. Users will also never have to deal with reformatting reports ever again since this scale already observes the GLP, ISO, 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.
