BOOKOO Themis Ultra Coffee Scale

Overview The BOOKOO Themis Ultra is a mid-size coffee scale designed to work across espresso, pour-over, and batch brewing. It sits in the space between tiny espresso-only scales (like BOOKOO’s own Themis Mini) and larger kitchen-style scales, with a footprint of 127 × 112 mm that fits on most espresso machine drip trays while still being wide enough to hold a pour-over dripper or two cups under a double spout. The display shows up to three metrics simultaneously, including weight, timer, and flow rate, depending on which of the four built-in modes you select: Weight, Flow, Ratio, or Auto. In Auto mode, the scale tares when you place a cup and starts timing automatically when it detects liquid. Via Bluetooth, the scale syncs with the BOOKOO N app, Beanconqueror, or Odyssey Espresso for live flow graphs, brew logging, and recipe ghosting. It also integrates directly with smart espresso machines like the Decent Espresso and Gaggiuino for auto-stop at a target yield. Why IP67 matters on a coffee scale Most coffee scales are rated IPX4 (splash-resistant) at best, and many have no water resistance at all. The Themis Ultra carries a full IP67 rating, which means it can be submerged in water without damage. In practice, that means you can rinse it under a tap after a messy backflush, wipe steam residue off without worry, or clean it thoroughly between sessions. For anyone who has lost a scale to a spill or to steam corrosion over time, this is a meaningful difference. The body is made from transparent heat-resistant polycarbonate (not glass) with an internal steel plate, which also makes it more resistant to drops than glass-topped alternatives.
