No. None of our scales are waterproof. The Acaia Lunar is water resistant.
The Acaia Lunar's electronic parts are coated with a water-resistant spray. All these parts are screwed into the top of the scale. Any water that enters via a steam wand will go up the sides and condense into the base. The top's LCD screen is sealed against water entry.
If water does happen to enter and it affects the scale, you'll see H20 begin to flash. The underscore (__) shows which button side the water is affecting. You can let the scale sit and dry out.
The Acaia Lunar comes with a 2-year manufacturers warranty. It includes protection against water damage.
The Lunar is designed to prevent liquid damage. If you’ve been following our technical blog posts, you’ll know that varying temperature is a major factor in scale accuracy. If a large amount of hot liquid ends up on the Lunar, the scale will live. But the accuracy will be affected until it returns to room temperature. The aluminum-constructed Lunar allows the heat to escape the body as quickly as possible.
Waterproof vs Water Resistant
To claim a product is waterproof, you are required to test and certify them. This includes operating them underwater. Since the Acaia Lunar cannot be operated underwater, we do not claim that it is waterproof.
