Our technology of density meter to determine alcohol content is used for quality control in production of not only wine, sprits or beer, but also disinfection solution and hand sanitizer. The ethanol content in disinfectant solution and hand sanitizer is generally adjusted to be around 70% to exert the best bactericidal effect.Today, the market demand for these solutions is increasing under the global COVID-19 pandemic . On the other hand, it can't be denied that there are a growing number of companies selling products that label the incorrect percentage of ethanol content, which is not enough to disinfect.We believe that our alcohol meter is the best instrument for checking the ethanol content in a solution.
