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 Calibration Weight follows the same aesthetic as our scales, with the Acaia logo and laser-etched on the top and side. The stainless steel material is durable to ensure accuracy over time, and the weight comes with an EVA foam case for protection during travel.
• Machined from stainless steel for long-term durability
• Includes custom-fit soft travel case for protection
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. If you would like to read more about how to calibrate your scale, why we recommend it, and how often to calibrate,
What is calibration and why is it important?
Calibration, quite like regularly cleaning your grinder, falls within the basic maintenance of your equipment. In simple terms, calibration is the processing of checking the reading of a scale using a reference weight for comparison. In the process, the scale’s reading error is defined as the difference between what the scale is displaying and the true value of the weight on top of it. This is why it is vitally important to use certified calibration weights.
During a scale’s smart or quick calibration, it will relearn the true weight of the calibration weight placed on top of it and use it as a reference point. Some of the most precise scientific balances or scales are calibrated before each and every measurement. The more precise the calibration weight, the more precise future readings will be. The goal is to minimize any measurement errors.
A quick or smart calibration can easily be performed on any of our balances. Using one size calibration weight, it will perform a general calibration around the range. A linear calibration is a more thorough method that makes sure your scale is calibrated in the lower, middle, and upper ranges of its weighing capacity. Three F2-class 500 g weights are required to perform this calibration.
So why in Calibration important?
The reason it is important to calibrate is to make sure that your scales stay as accurate as possible. Regular calibration over time will maintain this. The benefits of a calibrated scale are cost efficiency, reliability, and of course great tasting coffee that is duplicatable!
It's possible to make good coffee with volumetric measurement, or even a scale that has gone out of calibration, thanks to the fact that coffee brewing is based around ratios. It's possible to make incredible coffee with even rudimentary tools. However, when it comes time to explain to someone else how to reproduce that exceptional coffee, having instruments that produce the same accurate measurements makes it much more likely that you'll be successful.
This doesn't just apply to telling another person how to reproduce the great cup of Yirgacheffe you just brewed. It also goes for you, in the future. If you've found a way to brew a coffee that you love, you'll want to be able to reproduce it a month later, no matter where you are and what equipment you end up using.
How often should I calibrate my Acaia Scale?
The Acaia scales are designed with a lab-balance-grade level performance. The higher the resolution is, the more frequent you need to calibrate the scale.
For example, a scale that weighs from 0.001 g (1 mg) in the lab is required to be calibrated "each time" you weigh an object.
For Acaia scales, we have a high resolution that we would recommend a daily calibration for commercial use (cafes). If you're a home user, every month will work. And if you take the scale on your travel adventures, you should calibrate at the new location.
What kind of calibration weight should I use?
Acaia’s smart calibration allows it to calibrate at 100 g, 300 g, 500 g, 1000 g, and 1500 g. If you decide to calibrate your scale, it will only be as good as the accuracy of the calibration weights you use. It is recommended to use standard weights of 100 g, 500 g or 1000 g.
The Acaia Lunar and Cinco comes with a 100 g weight. We sell a 500 g weight in our store.
