The Globe Scientific GBP-3101 is a portable precision balance with 3100 g capacity and 0.1 g readability, externally calibrated. It weighs up to 3100 g, for general sample, reagent and bulk-material weighing where milligram resolution is not needed. An internal battery lets it move from bench to bench, or into the field, without a power outlet. This listing includes an ISO/IEC 17025:2017 accredited calibration certificate.

Frequently asked questions
How is the GBP-3101-CT calibrated?
The GBP-3101 is calibrated externally with a reference weight of known mass. This listing includes an ISO/IEC 17025:2017 accredited calibration certificate.
Can the GBP-3101-CT run without mains power?
Yes. It has an internal rechargeable battery rated by Globe for up to 15 hours, with automatic shut-off and a low-battery indicator.
What do the GBP-3101-CT’s repeatability and linearity figures mean?
Repeatability of 0.1 g is how closely repeated weighings of the same load agree. Linearity of ±0.3 g is the largest deviation from the true mass across the weighing range. Both are Globe’s specifications for the GBP-3101.
How big is the GBP-3101-CT’s weighing pan, and how fast does it settle?
The pan is 128 x 128 mm and Globe rates stabilization at 2 sec. The balance itself measures 260 x 160 x 68 mm.
