HARIO Polaris Scale Key Specs
Weight Capacity: 78.6 oz (2,000 g)
This limit allows you to weigh large batches of beans or multiple cups of brewed coffee at once. It supports standard home brewers who prepare two to four servings simultaneously. If you often brew for a group or batch brew for the week, this capacity prevents overflow errors. Smaller scales may cap out at 500 g, forcing you to weigh in smaller, less efficient increments.
Dimensions: 5.0 x 6.5 x 1.1 inches
The platform size accommodates most standard pour-over drippers and glass servers. You can place a V60 or Kalita Wave directly on the surface without it overhanging the edges. The 1.1-inch height keeps the profile low, which may improve stability during pouring. Check your specific dripper diameter to ensure it fits comfortably within the 5-by-6.5-inch footprint for accurate centering.
Platform Material: ABS resin, acrylic resin
These materials provide a smooth, flat surface that is easy to clean and resistant to staining from coffee oils. ABS resin offers durability against drops, while acrylic adds a clear, rigid structure. This combination ensures the platform remains level for precise measurements. Unlike metal platforms that can dent, plastic composites maintain their shape over time, supporting consistent weight readings for your daily brew routine.
Product Weight: Approx. 15.2 oz (437 g)
The scale itself is light enough to move between counters but heavy enough to remain stable during use. You will not need to clamp it down or weigh it down with extra items. This mass helps prevent sliding when you pour water from a gooseneck kettle. Compare this to ultralight travel scales that may tip easily; this weight offers a balance of portability and steadiness for your kitchen setup.
