When we’re pulling espresso shots in our daily routine, it’s pretty common to use both a dedicated espresso scale and a separate shot glass.But every time I go through that setup, it feels a bit cumbersome. Or maybe it’s just that there are too many tools cluttering the bar. You need a compact espresso-specific scale, plus a measuring cup—or even one with oil-filtering features. If you could combine the two into one, it would simply make more sense and be far more practical.
Some people might say, “Haven’t products like this been around for a while?” And that’s true. I’ve used similar all-in-one scales before. The key difference here, though, is that the cup and the scale are still designed as separate components, and the cup itself is made of easy-to-clean stainless steel. That alone makes it significantly more practical than some of the versions I’ve used in the past. At its core, it’s no different from a standard scale-and-cup setup—but the integrated design makes your espresso station look cleaner and helps streamline the workflow.
This coffee scale uses gravity-sensing technology to track real-time weight changes during extraction. The moment liquid starts dripping into the cup, the timer automatically kicks in. When the extraction stops and the flow stabilizes, the timer stops as well—no manual input needed. It also features a dual-range high-precision sensor system, measuring from 0.2g to 500g. It’s sensitive enough for fine adjustments, and the readings remain stable without digital drift, ensuring accuracy throughout the entire brewing process. The cup itself holds up to 100ml and includes internal measurement markings at different levels.
The scale comes with a built-in LED display and touch controls. Personally, though, I think the vertical viewing angle isn’t ideal—you have to shift your perspective slightly to read the screen while working. If the display were angled, it would be much easier to read at a glance while standing. So from a usability standpoint, this might be a small drawback for JOINOUT in terms of visibility during real-world use.
Thanks to the modular design, the stainless steel cup can also be used independently, which adds some flexibility. The device is powered by a 300mAh rechargeable lithium battery, offering up to 14 hours of continuous use. And of course, it includes the standard scale feature of switching between grams and ounces, making it adaptable to different workflows and preferences.
At the bottom, there’s a non-slip base that keeps everything securely in place during brewing. Even on smooth surfaces, it won’t slide around, helping maintain consistent measurements. There’s also an optional pure titanium cup version available—lighter, more corrosion-resistant, and with a premium feel. That said, the standard stainless steel cup is already excellent. Both options are designed with safety, durability, and a refined coffee experience in mind.
