How accurate and sensitive is the A&D Weighing GP-61KS Precision Scale compared to other 100mg readability balances available?

GP-61KS Readability

With a readability of 100mg, the GP-61KS is designed to handle most simple weighing tasks within your lab. The GP-61KS is part of the A&D Weighing GP series ideal for applications like laboratory testing and chemical analysis.


How precise is the GP-61KS Precision Scale against other 100mg readability balances?

GP-61KS Repeatability

The GP-61KS offers 200mg repeatability. Typically presented as standard deviation and important to persistently producing the same results when the same weight is put on the lab balance multiple times, repeatability is one factor that can show accuracy and validity.


What is the response time of the GP-61KS Precision Scale contrary to other 100mg readability balances?

GP-61KS Stabilization Time

The time that the GP-61KS balance takes to stabilize from the time you put your sample on it and displays results is 1.5 seconds.

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.
