Espresso enthusiasts, meet your new shot scale. Water-resistant and jam-packed with amazing features, the Acaia Lunar is the last shot scale you'll ever need to buy. It's time to stop throwing away lesser scales.

Yes, you can dump all the water you want on this bad boy - it's completely waterproof!

The coffee world asked for a better way to weigh their espresso, and it's finally here: Acaia's answer to the shot scale, the Lunar. The Lunar is compact, responsive, multifunctional, and perhaps most importantly, highly water-resistant. This is everything we love about the Pearl, condensed into a smaller drip tray-friendly package. The Lunar is the shot scale we've all been waiting for.

Leave it to Acaia to pack a scale with all the details we need, and then tack on a few more ever-so-useful functions we could only dream of having. The Lunar has multiple function modes that include the basic weight display and timer, as well as more advanced functions that include an auto-start/auto-stop timer based on the flow of espresso into the cup, as well as auto-tare function that zeroes out your cup about one second after it is placed on the scale.

Every experienced barista knows a little water in the wrong place is enough to kill your average shot scale, and so the Lunar uses a water-resistant coating on its circuitry - so your scale keeps on kicking even if you spill a full shot on top of it. Acaia backs this up even further with a two year warranty which includes water damage protection. Inside the scale are the same high-quality internals you can expect from Acaia, including an internal battery with a 20 hour life. The scale charges fully in just a few hours using a standard mini USB charging cable (included), and includes Bluetooth 4.0 connectivity to connect it to the Acaia Coffee app and the new slimmed-down Brewmaster app.

Also included with the scale are a pair of stick-on plastic feet to protect the bottom of the Lunar if you need to move it around frequently, a 100 gram calibration weight, and a heat-proof silicone pad which can also be used as a portafilter rest to weigh out your dose.
