My drip tray attaches to a scale of your choice. Currently, four scales are supported (Skale 2, Acaia Lunar/Pearl, Felicita ARC and the Decent Pill scale). Scale caddies are available for Skale 2, Acaia Pearl and the Decent Pill scale but not included. Instructions will be provided for how to obtain it.

If you don't have a strong preference on which scale to use, I highly recommend the Skale.

More info on the adapter plates:

Atomax Skale 2: Steel plate to replace the existing plastic weighing platform. This plate also doubles as a splash guard protecting the internal electronics.

Acaia Lunar: Aluminum cap which sits on top of the scale.

Acaia Pearl: Aluminum cap which sits on top of the scale.

Felicita Arc: Aluminum cap which sits on top of the scale.

Decent Pill: Aluminum plate which is adhered to the top of the scale. There are tabs on the plate to easily pop the plate off.

Recently, the Decent Pill Scale has become a popular choice. Please note, that scale is quite tall. This may cause some interference when sliding the scale under non-XL machines. Once slid into place, there would be no functional concerns.
