Battery / anti-freeze cleaning fluid tester

For testing the optimal liquid density of the battery, anti-freeze, windshield washer fluid and Adblue.
Includes case with liquid pipette and zero set screwdriver.

Measuring range:

• Coolant (antifreeze) -50 degrees to 0 degrees Celsius for propylene, ethylene and G11, G12, G13 coolant from, among others, VAG (Audi, Porsche, Seat, Skoda, Volkswagen)
• Adblue 30 to 40 % (also Urea and DEF)
• Battery acid charge level 1,100 to 1,400 Kg/l
• Wiper fluid -40 degrees to 0 degrees SRF

Works like binoculars: place a drop of liquid on the prism with the pipette. Close the lid. Look through the adjustable binocular opening. Read the value on the clear scale. Always rinse the prism with clean water, as battery acid is very aggressive. This extends the life of this tester. The tester can be easily calibrated by the user himself.
