AMG-S1 : Standard glass alcohol meter 0-100% (KL04305)

Standard glass alcohol meter with range 0-100% to determine the alcohol content in liquids.

Features :

• Alcohol meter with a measuring range of 0-100% alcohol.
• Reference temperature: 20°C

Procedure for measuring alcohol content:

The alcohol meter is calibrated to measure liquids at a temperature of 20°C. Pour liquid into the measuring cylinder and use a thermometer to determine liquid temperature. Subsequently, immerse the alcohol meter in the measuring container and the value you measure will display the % of alcohol. If the measured liquid has a temperature other than 20°C, it is necessary to calculate the alcohol % using the tables.

If the temperature of the measured liquid is lower than 20°C, the percentage of alcohol is added. At a temperature above 20°C, the percentage of alcohol is deducted.

Measured temperature Alcohol value
5°C + 5.3%
10°C + 3.5%
15°C + 1.8%
20°C 0%
25°C – 1.9%
30°C – 3.5%

Example 1.: If the temperature of the measured liquid is 20°C and the alcohol meter shows 45% alcohol, the actual alcohol concentration is 45%.
Example 2.: If the temperature of the measured liquid is 30°C and the breathalyzer shows 45% alcohol, it is necessary to subtract the value according to the table, i.e. 3.5%.

45% – 3.5% = 41.5% – the actual alcohol concentration is therefore 41.5%

Example 3.: If the temperature of the measured liquid is 5°C and the breathalyzer shows 45% alcohol, it is necessary to add the value according to the table, i.e. 5.3%.

45% + 5.3% = 50.3% – the actual alcohol concentration is therefore 50.3%
