The Bosch Automotive Service Solutions RR75240 Coolant/Battery Refractometer is designed for use by professional technicians to find specific gravity measurements for coolants and batteries, saving time and money

Just place a drop on the prism and it's immediately visible

Use this handy refractometer to test the amount of anti-freeze and coolant in your vehicle's radiator

It's perfect for quick service shops, rental car companies, collision repair and body shops, or any other facility that takes care of multiple vehicle makes

If a reading is not obtained within 15 seconds, simply clean the prism with a soft cloth and try again

It can be used with most coolants, engine or transmission oils as well as distilled water, ethylene glycol, propylene glycol, R12, R134a and PAG oils

This compact, durable tool is easy to use and features a protective plastic carrying case

The level of anti-freeze or coolant can also be viewed from behind the device without removing it from its protective case

It also identifies battery electrolyte levels and is perfect for checking transmission fluid levels too!

The coolant/battery refractometer is an essential tool for professional automotive technicians to ensure a proper coolant concentration and to efficiently troubleshoot battery problems

The Bosch Auto Service Solutions Coolant/Battery Refractometer is a fully automatic, digital instrument that measures the freezing points for both coolant and battery electrolyte fluids, as well as the specific gravity of both types of fluids

The easy-to-use scale can quickly determine the concentration of antifreeze and water in a vehicle

The BOSCH RR75240 is an economical tool that will perform the functions of a conventional hydrometer without removing the cap or siphon tube from the container

The refractometer is also used to measure the amount of water and battery fluid levels in automotive batteries

A quick, inexpensive way to check the level of antifreeze in your vehicle's cooling system

The Bosch Automotive RR75240 Coolant/Battery Refractometer can help prevent costly breakdowns or damage from neglect or improper maintenance

Just place a drop of liquid on the prism, look through the eyepiece and read the scale

Now you can test coolant and battery electrolyte fluids with a single tool

The BOSCH RR75240 Coolant/Battery Refractometer is designed for measuring the specific gravity of engine coolant or battery electrolyte

When used to test batteries, the device provides an accurate assessment of electrolyte strength and allows technicians to pinpoint problems with deteriorating cells

It provides an accurate reading in seconds, allowing you to determine when a service is needed

You can test any brand of coolant or antifreeze, including Ethylene Glycol, Propylene Glycol, Urea, and all types of Silicates

The BOSCH RR75240 Coolant/Battery Refractometer is an optical instrument used to measure the concentration of antifreeze in coolant solutions

This coolant/battery refractometer measures the freeze point and conductivity of coolants and battery electrolytes

The Bosch Automotive Service Solutions RR75240 Coolant/Battery Refractometer is used for testing the percentage of water in coolant

It also measures battery acidity, ensuring top performance from batteries after every use
