Balances

Buying Guide: Choosing the Right Precision Balance

Precision and analytical balances are selected primarily on readability and capacity. Laboratory work involving small, high-value samples typically needs an analytical balance with readability down to 0.1mg, while general precision weighing in production can often use a coarser precision balance. Consider the maximum sample weight you will need to weigh, as capacity and readability usually trade off against each other. If your samples are affected by moisture content, a dedicated moisture analyser may be more appropriate than a standard balance. Environmental factors such as draughts, vibration and temperature changes can all affect balance accuracy, so check whether a draught shield or vibration-resistant base is included. For regulated industries, ask about calibration certificates and whether the balance can be supplied with UKAS traceable calibration.

Frequently Asked Questions

What is the difference between a precision balance and an analytical balance?
Analytical balances offer much finer readability, typically to 0.1mg, and are used for small, sensitive samples, while precision balances suit general laboratory and production weighing.

Do balances need calibration?
Yes, we recommend regular calibration, and UKAS traceable calibration certificates are available for balances used in regulated or quality-critical applications.

Can balances measure moisture content?
Yes, our moisture analyser range is designed specifically to measure moisture content alongside standard weighing.

What affects balance accuracy?
Draughts, vibration, temperature changes and an uneven surface can all affect accuracy, so balances are best used on a stable bench away from airflow.

Can precision balances be serviced or repaired?
Yes, Phoenix Scales provides service, repair and UKAS calibration for balances and moisture analysers, helping laboratories and production sites maintain accurate, traceable results over the life of the equipment.
