HARIO Polaris Scale – Precise Coffee Scale for Perfect Brewing

Achieve Coffee Expertise with Hario Polaris

The Hario Polaris coffee scale is designed for those who want consistent, precise, and flawless brewing every single time. Whether you are making pour-over, Aeropress, espresso, or larger batches, this digital coffee scale helps you fine-tune your technique, control your coffee-to-water ratio, and create coffee with optimal taste and balance. 

Accuracy to the gram – Perfect coffee control

The Hario Polaris digital coffee scale measures accurately up to 2000 grams and displays weight with 0.1 g precision in the lower ranges, so you can dose coffee and water exactly according to your preferred brew.
This high level of accuracy is essential when working with small amounts of coffee or looking to optimize your brew profile to avoid over- or under-extraction.

Built-in timer – Keep track of brew time

With a timer that counts up to 9 minutes and 59 seconds, you can monitor extraction time without using a separate device.
The timer function is particularly useful for pour-over methods and time-based brewing techniques where time and weight work together to create a perfect cup of coffee.

Smart Ratio function – Eliminate the guesswork

Polaris introduces an innovative ratio function that automatically calculates how much water you need based on the amount of coffee used.
This means that no matter how little or how much coffee you choose, the scale shows the ideal water amount and percentage, allowing you to achieve the correct brewing ratio without manual calculation.

Percentage display – Follow the brew

The percentage display shows how far along you are in your brewing process in real-time – from 0% to 100%.
It is an intuitive way to keep an eye on how much water you have added, which creates a more consistent and reliable brew.

User-friendly and intuitive operation

The Hario Polaris coffee scale features a simple and easy-to-read display and intuitive buttons, so you can switch between weight, timer, and ratio functions without hassle.
The minimalist setup means that you can quickly get started with brewing, even as a beginner.

Compact design for home and café

With dimensions of 127 × 165 × 28 mm and a weight of approximately 500 g, the Hario Polaris is both space-saving and portable – perfect for your kitchen counter or home coffee corner.
The robust base with non-slip silicone rubber ensures stable weighing, even when using larger servers or brewing at a fast pace.

Compatible with various brewing methods

Hario Polaris works excellently with pour-over brewing (like V60), Aeropress, Chemex, and other manual methods, because it gives you control over both weight and time – the keys to consistent coffee.
You can quickly switch between classic weight display and Polaris mode, allowing you to adapt the scale to your brewing style.

Durable and practical – Ready for daily use

The Polaris scale is powered by 3 AA batteries and provides many hours of precise measurement without frequent battery changes.
