KGM KYOTO ELECTRONICSAPDA-0197ov enLMANUFACTURING CO.，LTD. Application Note Determination of ethanolconcentration in disinfectionsolution by Portable Density/ Specific Gravity Meter Industry Instrument Measurement method ChemicalPortable Density/ Specific Gravity MeterResonant frequency oscillation 1. Scope This is an example about determination of the ethanol concentration with volume percent incommercial disinfection solution. The alcohol meter can be used enough for determination of pureethanol concentration on production process. Note： this measurement result does not completely match the label value of disinfection solutionbecause the commercial products contain additives like glycerin， etc. 2. Apparatus ·Portable Density/ Specific Gravity Meter DA-130N 3. Sample ·Disinfection solution 4. Reagent ·Pure water 5. Procedure Place sampling nozzle into beaker.23 Slowly pull the sampling lever with the forefinger. After the icon Eisi s ddiissppllaayyeed， start measurement with [ok/meas.] key. 6.Measurement results Alcohol (wt%) Alcohol (vol%) S.G.
