What is Brix value of coolant?

Every coolant concentrate has its own unique Brix factor (also known as its refractive index factor or RI factor) which is a multiplier utilized in conjunction with a digital or optical refractometer reading. Brix factors range from 0.9 for emulsions, to 3.4 for synthetics.

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.

What is refractometer factor?

Refractometers are instruments used to obtain a °Brix reading, which measures the oil content present in a coolant mixture. Additionally, each coolant refracts light differently and therefore has its own specific multiplier, called a refractometer factor.

How do you read a refractometer scale?

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.

What does a refractometer read?

Refractometers measure the degree to which the light changes direction, called the angle of refraction. A refractometer takes the refraction angles and correlates them to refractive index (nD) values that have been established. Using these values, you can determine the concentrations of solutions.

What is Brix factor?

Degrees Brix (symbol °Bx) is the sugar content of an aqueous solution. One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by mass.

How do you calculate refractometer factor?

To find the correction factor on your own, divide the refractometer value (Brix WRI) by the hydrometer value (converted to Plato / Brix) . Repeat the measurements with different worts (across your next several brew sessions).

What are the units of a refractometer?

Its units are typically g/dl (g/100ml). These units may also be printed on the lid of the refractometer case (figure 3). The central scale is the refractive index scale (nD or ND).

What is the ratio for mixing coolant and water?

Generally speaking, a 50/50 mixture of water and antifreeze is a good place to start. However, when speaking in terms of climate, you may want to take temperature into consideration. For example, 50/50 may work best in more moderate climates where the temperature gets below 32 only on occasion.

What is refractometer correction factor?

Where do you read on a refractometer?

Point the front of the refractometer again toward a light source and look into the eyepiece. You will now see the line delineated at a different point on the refractometer’s internal index. Read the point on the index at which the line falls to determine the refractive index of your liquid sample.

How do you read the refractive index scale?

To read the index of refraction, depress the switch on the left hand side of the refractometer until you see the scale through the eyepiece. This is a view of what the scale will look like. The upper scale indicates the index of refraction. By carefully interpolating you should get 4 decimal place accuracy.
