Hario STS-300-W Coffee Scale Mug

This double-walled, vacuum-insulated stainless steel coffee mug is perfect for enjoying a full cup of coffee whether you're on the go, at the office, or in the outdoors. Designed with a built-in, ultra-small digital scale, this mug allows you to brew coffee while precisely measuring the coffee powder and hot water.

The scale can be easily removed and used independently, making it a versatile tool for various applications beyond just coffee preparation. With its high-performance capabilities, the scale can measure from 0.1 to 2,000 grams with an accuracy of ±0.2 grams for weights between 0.1 and 200 grams.

The mug's vacuum insulation ensures your coffee stays deliciously warm, maintaining a temperature of 77 degrees Celsius even after an hour with the lid on. This impressive thermal retention is achieved through the mug's stainless steel construction and ceramic coating on the interior, which also resists staining from coffee.

The automatic start mode on the scale allows the timer to begin tracking the brewing process as soon as it detects the start of your coffee preparation, providing a convenient and precise way to monitor the extraction. The scale has a count-up maximum time of 15 minutes and 00 seconds, ensuring you can time your coffee brewing with ease.

With a practical capacity of 10.1 fluid ounces (300 milliliters), this coffee mug is the perfect size for enjoying a full cup of your favorite brew. The charging time for the scale is 1 hour and 40 minutes, ensuring you have ample power for your on-the-go or office coffee needs.
