About measurement value
Refractometers measure the concentration of all dissolved solids in a solution.
For example, the PAL-34S Ethyl Alcohol Refractometer can accurately measure the concentration of ethyl alcohol if the sample consists only of water and ethyl alcohol. Any other substance(s) dissolved in the sample will affect the readings. The refractometer cannot differentiate just the content of ethyl alcohol.
Likewise, the PAL-Citric Acid is designed to measure samples that contain only water and citric acid. It cannot analyze the concentration of other types of acid that may be present in the sample. .
