What is an analytical balance?
Analytical balances and Microbalances are accurate and precise instruments used to measure masses. They require a draft-free location on a solid bench that is free of vibrations. Some modern weighing scales have built-in calibration masses and temperature monitoring to maintain accuracy.
Ideal for use within the medical and health industry, some trade approved analytical balances are necessary for producing accurate patient weight readings that can be monitored by doctors and other healthcare professionals.
Analytical balances are often known for their accuracy and expense, but here you will find a balance to suit all budgets. For more precise and consistent results, try combining your analytical balance with anti-vibration table .
How accurate is an analytical balance?
The accuracy or precision of an analytical balance is model specific and will usually range from 0.1mg to 0.1g readability. Whilst this proves to be one of the most precise digital weighing scale types on the market, it is worth noting that as a rule, the pan size and capacity will be smaller in comparison to precision balances and other types of digital weighing scale. Due to its high precision, the analytical balance is a preferred option for lab based applications.
How to calibrate an analytical balance?
To calibrate an analytical balance you will first need to know whether your balance uses internal or external calibration.
Analytical balances with internal calibration can be calibrated automatically by selecting the calibration option in your balance's setup/ calibration menu.
Analytical balances with external calibration will require approved calibration weights which need to be placed on the balance in sequence (using heavier weights to begin, such as 10g weights, moving through to more precise, lighter weights e.g 1mg). There are several Classes of calibration weights including M1, F1 and E2. Standard analytical balances require E2 class weights.
