What does a refractometer measure in alcohol?

A refractometer is a tool that many homebrewers use for measuring specific gravity when making beer. A small device, the refractometer is an optical tool that can measure the amount of sugar in your solution. A refractometer will allow you to find the specific gravity of your brew without much waste from the sample.

How is spirit strength measured?

The OIML system measures alcohol strength as a percentage of alcohol by volume at a temperature of 293.15 K [20.00 °C; 68.00 °F]. It replaced the Sikes system of measuring proof of spirits, which had been used in Britain for over 160 years.

What kind of alcohol refractometer for spirit alcohol volume percent?

It is designed for testing Spirit Alcohol Volume Percent, ideal for Brandy, Whisky, Vodka etc. Not recommend for wine or others which contains much sugar and other ingredients. It is a portable optical instrument for Bartender, Alcohol Retailer and Food Producing etc. The scale range is 0 – 80 %V/V (V/V – alcohol volume percent), division: 1 %v/v.

What can a refractometer be used to measure?

• Measurement of % sugar in fruit and vegetables provides information on quality and may be used as an indicator of harvest time, market value or use as a fresh or preserved product. • Refractometers are composed of a glass measuring prism where the sample is placed, which is covered by an illuminator flap or cover.

How is a glass prism used in a refractometer?

• Refractometers are composed of a glass measuring prism where the sample is placed, which is covered by an illuminator flap or cover. When light passes through a sample containing dissolved solids (such as sugars), it is interrupted, slows down and is bent or ‘refracted’.

How does a refractometer read the gravity of wine?

This feature is not available right now. Please try again later. A refractometer instantly reads gravity of unfermented wort, wine must, mead or fruit juice by measuring the degree that light passing through the sample is bent. Unlike a hydrometer, only a few drops are required for a sample.
