The Globe Scientific GBP-203 is a portable precision balance with 200 g capacity and 0.001 g readability, externally calibrated. It reads to 1 mg, a common choice for formulation, reagent preparation and sample weighing above analytical resolution. 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-203-CT calibrated?
The GBP-203 is calibrated externally with a reference weight of known mass. This listing includes an ISO/IEC 17025:2017 accredited calibration certificate.
How big is the GBP-203-CT’s weighing pan, and how fast does it settle?
The pan is ø 100 mm and Globe rates stabilization at 2 sec. The balance itself measures 260 x 160 x 68 mm.
How do I get weighing data off the GBP-203-CT?
Through its ports: 2 x RS232, USB-A, USB-B. It stores up to 100,000 measurements with date, time, mass and tare value.
What do the GBP-203-CT’s repeatability and linearity figures mean?
Repeatability of 0.002 g is how closely repeated weighings of the same load agree. Linearity of ±0.004 g is the largest deviation from the true mass across the weighing range. Both are Globe’s specifications for the GBP-203.
