FAQ

A precision balance measures mass using a mechanical or electromagnetic force restoration system:

  1. The sample is placed on the pan.
  2. The balance generates a counteracting force (usually electromagnetic) to maintain the pan at a constant position.
  3. The magnitude of this force is proportional to the sample’s mass and displayed digitally.

This principle ensures high accuracy, fast response, and stability, allowing even milligram-level differences to be reliably measured.

Proper calibration ensures measurement accuracy:

  • Internal calibration: Built-in calibration weight automatically adjusts the balance at the push of a button.
  • External calibration: Requires a certified external weight for manual or automatic calibration.

  1. Place the balance on a stable, level surface away from drafts, vibration, and direct sunlight.
  2. Turn on the balance and allow it to warm up if required (typically a few minutes).
  3. Calibrate the balance according to the manufacturer’s instructions (internal or external calibration).
  4. Tare the balance to zero before weighing your sample.
  5. Place the sample gently on the pan and wait for the reading to stabilize.
  6. Record the weight once the measurement is stable.
  7. Clean the balance pan after use to maintain accuracy and prolong lifespan.

Precision balances must strike a balance between readability (precision) and maximum capacity:

  • Higher precision (finer readability) usually comes with lower maximum capacity.
  • Higher capacity models typically have coarser readability.

Guideline:

  1. Determine the typical weight of samples.
  2. Identify the smallest weight increment you need to measure accurately.
  3. Choose a balance that meets your precision needs while comfortably handling your sample weight range.

While both analytical balances and precision balances are designed for weighing, they serve different purposes. Analytical balances provide sub-milligram accuracy and are highly sensitive to environmental conditions, making them ideal for micro-weighing and high-precision laboratory applications. Precision balances, on the other hand, are suitable for general weighing tasks with larger capacity but lower resolution. For micro-weighing, a precision balance cannot reliably replace an analytical balance due to its limited readability and stability. For a clear overview of the differences, you can refer to the comparison table of analytical and precision balances.
