Capacity - How much do you need it to weigh up to? Make sure you have enough capacity to weigh the product plus the weight of any container that you use on the balance.
Division Size or Resolution? - Choose the increment size, also known as readability, resolution or division size. This is the smallest unit the balance will display: i.e. 0.1g increment size means the display on the balance will increment by 0.1g at a time
Accuracy - No measuring device is 100% accurate and typically the accuracy of weighing balances when new and used in a stable environment is approximately +/- 2 x division size throughout the weighing range.
If you need an accuracy of +/- 0.1g, a balance with an increment size of 1g would not be able to provide this tolerance and although a balance with a division size of 0.1g will give you a reading that is suitable, if you take into account the maximum error or accuracy then a balance with a 0.01g resolution (readability) is required
Where will you use it? - Given the high resolutions on some electronic balances, small things can affect your readings. Vibrations from the street outside, any draughts in the area and the temperature of the room can all have an effect on your measurements.
Features & functionality - What features or built-in applications do you need?
If you are liquid filling you will need a balance with a fast display update to ensure that you do not overfill
What units do you want it to weigh in? Grams, ounces, milligrams, grains or troy ounces?
You may need a parts counting function, so you can count very small items into a container and the balance will tell you when you have reached the correct amount
A check weighing function will confirm the item or set of items is within specification
Rapid have a full range of Analytical and Counting Balances as well as Hanging, Platform, Portable and Precision Scales.
