The Globe Scientific GBT-603 is a precision balance with 600 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. It is part of Globe’s GBT series, operated from a color touchscreen. This listing includes an ISO/IEC 17025:2017 accredited calibration certificate.

Frequently asked questions
How is the GBT-603-CT calibrated?
The GBT-603 uses external calibration: it prompts you for a pre-defined reference mass and calibrates against it. For hands-off calibration, Globe makes internal-calibration versions (model numbers ending in C). This listing includes an ISO/IEC 17025:2017 accredited calibration certificate.
What do the GBT-603-CT’s repeatability and linearity figures mean?
Repeatability of 0.0015 g is how closely repeated weighings of the same load agree. Linearity of ±0.003 g is the largest deviation from the true mass across the weighing range. Both are Globe’s specifications for the GBT-603.
How do I get weighing data off the GBT-603-CT?
Through its ports: 2 x RS232, USB-A, USB-B, Ethernet. It stores users, products, weighings and formulations, and prints reports with a signature line.
How big is the GBT-603-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 333 x 206 x 100 mm.
