Analytical balances are used to measure mass with an extremely high level of accuracy and precision since unlike spring scales, they are not affected in any way by changes in gravity local to the area. You can also buy the best analytical balances online.
The gravity field's strength generated by the movement of the balance is not going to affect the mass of the measurement, since the forces on each side of the beam for balance are equally affected by gravity's pull.

The weighing pans used by a high-precision (.01 mg or higher) balance are housed in an enclosure that is transparent and has doors to ensure dust doesn't accumulate and any airflows that circulate through the room will not interfere with the balance's functioning.
An enclosed safety enclosure that is vented, and an analytical balance, which is equipped with specially designed acrylic airfoils ensures a smooth, non-turbulence airflow that permits weighing quantities as small as 1 microgram, without fluctuation or loss of the product.
The samples should be kept a room temperature, to prevent natural convection from forming circulation inside the enclosure, which may impact the process of weighing.
Precision in the analytical analysis is achieved by making sure that there is the same weight on the beam by subtracting weight from the exact side that the sample is added.
The balance is then achieved through a tiny spring force instead of subtracting weights fixed to the beam. This allows for the additional weights to function to the balance as an exact adjustment.
Balances are used to compare the weight between two objects while a scale measures its mass for an object or group of objects. The most commonly used types that are in use currently are beam balances, top-loading balances analytical balances, and precise scales.
