WebGlycol Refractometers for Automobile Coolants and Battery Acids Zebra Glycol Refractometers have a temperature scale to read the protection rating of an ethylene and propylene glycol mixture as well as battery acids. These units … WebRefractometers measure the degree of this direction change, called the angle of refraction. The reading on the measuring scale, recognizable by a clear color separation on the scale, indicates the concentration level of the emulsion.

WebSep 10, 2003 · A dark appearance is indicative of the presence of emulsified tramp oil, which cannot be effectively removed with any recycling technique. High-pressure coolant systems, because of their aggressive agitation, require close attention. Good emulsions are either semitransparent or milky white with a sharp, rather than diffused, refractometer reading. service ontario verify address

How to Use a Refractometer to Test Glycol Concentration

WebAug 4, 2014 · Only a pure soluble oil coolant will read out 1:1 for concentration, and most of those have additional additives that skew the reading. The correction factor is usually given by the coolant manufacturer as a multiplier, such as 1.2, 1.6, etc. Synthetic coolants will have the highest factors, semi-synthetics less so, and soluble oils usually ... WebBRIX Factors and Refractive Readings 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. A Brix factor WebPlace your sample on the reflecting prism and look through the eyepiece to view the concentration on the internal scale. Concentration meters with automatic temperature compensation standardize readings at 68° F to prevent inaccurate results in … service ontario transfer vehicle to family
