The Hydrometer 3 Scale is a precision measuring tool used to determine the specific gravity of your brew, helping you track fermentation progress and estimate alcohol content. Suitable for beer, wine, and spirits, it’s an essential tool for improving consistency and understanding your results.

Measure fermentation with confidence

A hydrometer allows you to take accurate readings before and after fermentation, giving you a clear picture of how your brew is progressing. It removes guesswork and helps you know exactly when fermentation is complete.

• Measures specific gravity to track fermentation
• Helps estimate alcohol content (ABV)
• Suitable for beer, wine, and spirits
• Simple, reliable tool for consistent results

Designed for everyday brewing use

The 3-scale design provides clear readings across different brewing applications, making it easy to interpret results whether you’re brewing beer, making wine, or preparing a wash for distillation.

It’s a straightforward tool that quickly becomes part of your standard brewing process. Read more here  how to use a hydrometer

Where this fits in your setup

This hydrometer is used during fermentation to check starting gravity (OG) and final gravity (FG). It’s ideal for brewers who want more control over their process and more consistent results from batch to batch.

Key details

Type: 3-scale hydrometer designed specifically with colour coding to be easy to read and easy to use
Applications: Beer, wine, and spirits
Measurements: Specific gravity, potential alcohol, and sugar levels

Provides clear, accurate readings to help you monitor fermentation and calculate results.

What to expect in use

• Accuracy: Reliable readings for fermentation tracking
• Ease of use: Simple to read and interpret
• Control: Better understanding of your brewing process
• Results: More consistent and predictable outcomes

Compared to brewing without a hydrometer

Without a hydrometer, it’s difficult to know when fermentation has finished or what alcohol level you’ve achieved. Using one gives you clear data and better control over your brewing process.

Frequent questions

Q.What does a hydrometer measure?

A hydrometer measures specific gravity, which tells you how much sugar is in your liquid and how fermentation is progressing.

Q.How do I calculate alcohol content?

Using a simple formula, you can calculate the approximate alcohol percentage (ABV) of the finished beer.

(Original Gravity OG – Final Gravity FG x 1000) x 0.14

this gives you an estimate of alcohol by volume (ABV).

Q.Do I really need a test flask when using a hydrometer?

A test flask is recommended as it makes it easier to take accurate readings without contaminating your batch.

Q.Is a hydrometer suitable for beginner brewers?

Yes, this hydrometer is easy to use and is a great tool for beginners looking to improve their results.

Q.Can I use this hydrometer for distilling?

Yes, it can be used to measure gravity in washes before distillation, helping you understand potential alcohol levels.
