The reading on the measuring scale, recognizable by a clear color separation on the scale, indicates the concentration level of the emulsion. For some metalworking fluids, the reading on the measuring scale needs to be .The analog refractometer scale is subjective, meaning that two or more people looking at the scale are likely to report different readings depending how they view the scale. You also need to bring the glycol near your face to take a reading. Brix refractometers are temperature compensated for sucrose not glycol.
This direct reading relationship holds true ONLY for sucrose solutions. So, if you are measuring sucrose solutions with your Brix refractometer, you may read percent sucrose directly on the Brix scale. If you are reading non-sucrose solutions on the Brix scale then the readings must be converted into solution concentrations to be useful to the . To make the conversion easier, refractometers are available with scales that are calibrated to read the desired value, in this case, percent salinity. The concentration of a coolant, cleaner, or other aqueous solution is usually determined in the field with the use of . Instant Reading Result: Just need 2-3 drops of solution and a few seconds, you can get accurate readings. . 4-in-1 DEF Antifreeze Coolant Refractometer for Automobile Antifreeze System, Diesel Exhaust Fluid, Battery Acid and Windshield Washer Fluid. 4.6 out of 5 .The sample must spread all over the prism surface. Do not dip the refractometer into the coolant sump. Do not place the refractometer under a coolant stream. Not following these directions can damage the refractometer prism and calibration. Look at the scale through the eyepiece and read the scale where the boundary line intercepts it.

A refractometer is used to measure the freezing point of vehicle coolant, washer fluid, and potentially also testing battery electrolyte.This short video dem.
When calibrating a refractometer, it’s imperative to calibrate the refractometer with the same water you’re using to mix your coolant. Everyone’s water is different, but you’ll want the refractometer to read “0” with your specific water BEFORE measuring the concentration of the coolant. To calibrate an analog refractometer:
The instrument also has its drawbacks in that it measures the refractive index of the total solution, not just a single component. Therefore, refractometer readings can be inaccurate when the system uses hard water with a high mineral content or when tramp oil is present. It is important to frequently recalibrate the refractometer using shop water.
Remember, refractometers read on a Brix scale rather than actual percent. To get the actual percent, you must multiply the refractometer reading by your coolant’s refractive index (on product data sheet). With most soluble oils the index is 1, so a refractometer reading of 5 multiplied by an index of 1 = 5% concentration. Refractometer is an instrument used to determine concentration. It uses light to test the concentration of liquids as the light will pass from one medium to another. When light passes through the liquid, it is partly diverted by the dissolved solids in the liquid.second reading. The specific reading depends upon the particular coolant used and the dilution ratio. A 5.5 percent Brix reading is shown in Figure 3. 6. Record this Brix percentage reading of fresh coolant mix as the baseline reading. IMPORTANT: Over time water in the coolant mix evaporates and the refractometer reading will increase.After the coolant has separated poke a hole in the side of the cup and use the coolant that streams out to take your reading. This will insure that the refractometer reading is accurate. 2. Remove Tramp Oil • When tramp oils fall from the machine and into the sump they form a float-ing seal that prevents air from reaching the coolant underneath.
If it reads 5, then you know the conversion is 2. That means anytime you read the coolant in the tank with a refractometer, you multiply the reading x 2 to know the % by volume concentration. Indexes can range from as low as 0.8 to as high as 4 or 5. The index is important if you are relying on the refractometer for measuring concentration. The refractometer readout shown above is measuring 30 degrees Brix. Other Types of Refractometers. Digital refractometers require a drop of the tested solution to be placed in a well. That well is illuminated by a light .

To test coolant with a refractometer, follow these steps: Extract coolant or fluid from your machine using a dropper. Place 2–3 drops of coolant onto the prism of the refractometer and secure its cover plate. Be sure there are no dry spots or air bubbles beneath the cover plate's surface, as this can effect your reading.The Extech RF41 portable battery acid and coolant refractometer is a high precision optical instrument from Extech company.
