As alcohol meter is fragile products，we’ll try our best to pack it well.

Before open the dispute or feedback，please contact with us，we\'ll resend you the damaged products or refund you some money back!!!

 

First， the amount of alcohol alcohol concentration was measured only at standard temperature (20 Celsius) is the actual concentration of alcohol. However， in practice the temperature of alcohol are not standard temperature 20 Celsius， so you need to nonstandard temperature measured alcohol concentration conversion to standard temperature in degrees is obtained the actual concentration of alcohol. Conversion table is prepared for this purpose.

Second， the scope of application of the surface temperature 0 ~ +40 Celsius.

Third， use:

• The predicted amount of alcohol first poured into a glass measuring cylinder (cylinder capacity of not less than 300ml as well) There should be no dirt or alcohol turbidity.
• Wipe the thermometer set in the glass graduated cylinder (alcohol temperature should be within the range 0 ~ +40 Celsius or should be heating or cooling)， and then 30 to 60 alcohol wipe sailed sank glass cylinder count， which occurs when three conditions:

     a: the indexing level scale range， so be ready degrees.

 b: liquid level below the dividing ruler or alcohol meter skew， then can remove      the alcohol meter replacement 0-30 specifications;

 c: level higher than dividing ruler or alcohol meter sink to the bottom， then        remove the alcohol meter should also replace 60 to 100 specifications;

• The reading when the liquid level within the indexing ruler stand for 5 minutes before reading， reading position is tangent to the liquid surface and sub-degree scale where (press edge reads) alcohol meter showing the value of a note while reading take a thermometer showing the value.
• In the conversion table look-up to find a note of the lateral alcohol meter showing the value of the longitudinal conversion table to find a thermometer showing the value， both found， look at alcohol meter showing the value down from the investigation， showing the value of the thermometer From left to right the investigation， both the value at the cross that is want to measure the actual concentration of alcohol.

 

Example: in a glass measuring cylinder with alcohol alcohol concentration was measured at 61 degrees， with the thermometer measured the temperature is 10 Celsius alcohol alcoholic look-up table of the actual concentration of 61.7 degrees.
