Auxiliary tools

nbsp;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

nbsp;

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.

Set:

• Three scale refractometer
• Solid, comfortable case with sponge
• Pipette for taking and putting liquid on the sight glass
• Microfiber cloth for cleaning the speculum and lens
