INTENDED USE:

• 
  
  
• determining the freezing point of ethylene glycol aqueous solutions in cooling systems in cars, trucks, etc.
  
  
• determination of the freezing point of water solutions of propylene glycol in cooling systems in heating/solar installations
  
  
• determination of the electrolyte density in lead-acid batteries, e.g. used in the automotive industry
  
  
• determining the concentration of ADBLUE and the freezing point of windscreen washer fluid
  
  

 



A refractometer is a sensitive optical instrument used to test the freezing temperature of coolants and to determine the quality of the electrolyte in lead-acid batteries. The substances tested are hazardous to health, so it is absolutely necessary to avoid contact of the tested liquid with the skin.
