A precision scale needs a precision calibration weight to match, so we decided to build our own. Ensure that your measurements are the same as those of your collaborators! 

The Acaia 500 g Calibration Weight follows the same aesthetic as our scales, with the Acaia logo and laser-etched on the top and side. Acaia calibration weights are built to F2 class equivalent standards (± 0.0075 g) in our own facility. The stainless steel material is durable to ensure accuracy over time, and the weight comes with an EVA foam case for protection during travel.

Why is calibration important?

Acaia scales are precision instruments. The weighing sensor responds not only to weight, but also to temperature effects, surface tilt, gravitational influence, voltage bias, etc. In order to rule out external factors and maintain the highest weighing accuracy of the scale, periodic calibration is advised. This procedure can be completed with a standard calibration weight like the one seen here.

For best results, we recommend calibrating scales on a regular basis, as well as whenever they are transported or moved to a new location.
