High precision alcohol content tester ALM-155

GB 5009.225-2023 National Food Safety Standard Determination of Ethanol Concentration in Alcohol and Edible Alcohol
The fourth method is the U-shaped oscillating tube digital density meter method
Injecting the sample into the U-shaped oscillating tube measuring cell of the digital density meter, the oscillation frequency or period of the U-shaped tube also changes due to the change in the mass of the oscillating tube. The density of the sample at 20 ° C can be measured by using the oscillation frequency or period of the sample at 20 ° C and the instrument constant. By comparing the density of the alcohol aqueous solution with the ethanol concentration (alcohol degree), the ethanol concentration (alcohol degree) of the sample at 20 ° C can be calculated.
U-shaped oscillating tube digital density meter: analysis accuracy ± 0.00001g/mL, temperature control accuracy ± 0.02 ° C.

Working principle of high-precision alcohol content analyzer ALM-155:

The ALM-155 alcohol content measuring instrument is used to directly heat and distill alcohol samples to remove non-volatile substances from the samples. The distillate is then restored to its original volume with water, and the distillate is then drawn into the U-shaped oscillation tube of the digital alcohol concentration meter. Due to the change in sample density in the U-shaped tube, the vibration frequency will change. The instrument can automatically calculate the density of the distillate based on the vibration frequency of the sample distillate at 20 ° C. The instrument is equipped with the "Alcohol Water Solution Density and Ethanol Concentration (Alcohol Content) Comparison Table (20 ° C)" in GB 5009.225-2023, which can directly measure and display the volume percentage of ethanol concentration (Alcohol Content) in the sample.
Note: A binary mixture solution of ethanol and water can directly measure the alcohol concentration value.
