1 mg Top-Loading Precision Balance

1 mg 上称式精密天平

Buffer, media and small-batch formulation weighing usually needs milligram readability but more capacity than an analytical balance. This top-loader reads 1 mg up to 200–600 g, with repeatability of 1–2 mg and stabilisation in about 2–3 s. The 120–180 mm pan takes beakers easily. Choose internal or external calibration.

Readability: 1 mg
Capacity: 200–600 g
Repeatability (SD): ≤ 1–2 mg
Linearity: ±2–3 mg
Stabilization time: ≈ 2–3 s
