Can you test coolant with a refractometer?
Refractometers provide a quick, easy, and accurate way of testing and controlling coolant concentration.
How do you use a Brix refractometer for coolant?
Point the prism end of the refractometer toward a light source and focus the eyepiece until the scale is clearly visible. Read the scale value at the point where the dark and light portions meet. Below is an example of a concentricity the Brix scale as seen through the eyepiece.
What parameter of coolant is checked via refractometer?
In the automobile industry, a refractometer is used to measure the coolant concentration. In the machine industry, a refractometer is used to measure the amount of coolant concentrate that has been added to the water-based coolant for the machining process.
How do you measure coolant concentration?
The application is very easy: It involves simply adding a few drops of the coolant emulsion to the refractometer. The fluid’s index of refraction can then be read off. The coolant concentration in vol. % can be obtained by multiplying the result with the specific factor of the product.
How do I check coolant concentration?
The only accurate way to test for this concentration (and freeze point) is to use a refractometer. The old-style floating ball testers will not work properly with modern OAT, NOAT, and HOAT formulations. Generally, there are two types of refractometers that you should use with your modern coolant mixtures.
How do you calculate coolant concentration?
To find out how much you need to add, multiply the amount of coolant your vehicle can hold by the percentage of concentrated coolant you want to achieve. For example, if you want the coolant system to contain 50 percent of concentrated coolant, then you would multiply 0.50 x 12 to get an amount of 6 liters.
How is coolant concentration measured?
How to use and calibrate a refractometer?
Keep the prism free of fingerprints. Use a soft eyeglass cloth to keep it clean.
How to read and use a refractometer?
– It’s important to use pure water that is clean and free of extra particles. If the water has particles in it you won’t be able to accurately calibrate the refractometer. – The refractometer needs to be properly calibrated, or you’ll get an incorrect reading when you perform a test. – A refractometer looks like a small monocular that fits in your hand.
What is the best coolant to use?
Zerex G-05 Antifreeze/Coolant,Concentrated (ZXG051) Why we like it: Zerex coolant is inexpensive and highly effective,even in heavy-duty vehicles.
How to identify the correct coolant?
Find the coolant capacity of your vehicle. This usually ranges anywhere between 8 to 18 liters.
