Top 6 Questions You Should Ask When Buying a Lab Balance

1. What is the heaviest sample you will weigh (including container weight) and what is the lightest sample?

2. What is the required +/- tolerance of your lightest sample?

3. How many decimal places in grams do you require for the displayed weight?

4. What type of samples will you be weighing and do you need to take into consideration the size of the weighing surface or the securing of a tare container?

5. Is on-site service available from a factory-trained service technician?

6. Do you need to interface the balance to another device such as a computer, printer, bar code reader, etc.?
