A&D GR-202 Gemini Semi-Micro, 42/210 g × 0.01/0.1 mg
The A&D GR-202 Gemini dual-range semi-micro analytical balance provides 42 g × 0.01 mg / 210 g × 0.1 mg for laboratory weighing and sample preparation. Its built-in calibration mass and enclosed weighing chamber support a consistent daily routine.
Use the fine range for samples up to 42 g and the standard range for loads up to 210 g. Allow more settling time when working at 0.01 mg readability.
- Convenient access: the front lever opens a connected side door without reaching around the balance.
- Draft control: anti-static glass surrounds the weighing pan.
- Useful lab functions: counting, percent weighing, data memory and underhook weighing.
- Data transfer: standard RS-232C supports a compatible computer or printer; connection accessories are separate.

- Percent comparison and density work with appropriate accessories
Calibration & Connections
Warm up the balance for at least one hour and level it before use. Calibrate after moving it and follow the manual for the weighing environment and calibration procedure.
For a computer without a serial port, use a compatible converter and cable for the balance’s 25-pin RS-232C connection. A&D WinCT software is available to download. USB and Ethernet connections require separate accessories.
For fine-range work, follow the manual’s guidance on the fine-range breeze-break ring and control drafts, vibration, temperature differences and static.
