This instrument requires only a few drops of fluid for glycol testing and requires no adjustment for fluid temperature. For each percent salinity value, there is a corresponding angle of refraction. Freezbreaker is a propylene glycol based When rays of light pass from one medium into another, they are bent either toward or away from a … When the instrument is not in use, keep the cover closed to avoid scratching the prism. Grainger's got your back. To use your refractometer, place a drop of coolant or battery fluid onto the glass prism in the same way you used the distilled water for calibration. The scale is calibrated for use at 20±2°C with the graphs provided. A refractometer is a tool used for measuring concentrations of aqueous solutions.It has many applications across food, agricultural, chemical, and manufacturing industries. Get it as soon as Thu, Dec 31. • Sampling technique is critical in hydrometer use. Read the scale value at the point where the dark and light portions meet. Hand refractometers are made with a variety of different scales to measure dissolved solids in solution. What is a refractometer? How to use: The Refractometer has an adjustable eyepiece. When light enters a liquid it changes direction; this is called refraction. This easy-to-use optical instrument provides a quick and easy way to measure the Cooltreat ELC treatment performance based on the ethylene glycol … Use CoolTrak coolant test strips (kimdon.com) to test a sample of ethylene or propylene glycol based coolants. That well is illuminated by a light source, usually an LED light and the meter interprets the light transmission into refractive index or whatever unit of measure the instrument is programmed to read. Reading of the result ethylene glycol-based coolant (scale G11/12 - centre right scale) The result: the freezing point of the measured liquid is -26 °C (measured by refractometer … Battery powered – Allows use away from a power source. The scale is calibrated for use at 20±2°C with the graphs provided. The information contained in this article is intended for general information purposes only and is based on information available as of the initial date of publication. The Milwaukee MA871 Digital Brix Refractometer is … The sample should be wiped off with a moist tissue. We are interested in determining the level of ethylene glycol and triethylene glycol in the field and wonder if the PA203 is suitable to do that. Each compound has a specific index of refraction. The BRIX scale was actually developed for working with sugar related liquids (fruit juices, soft drinks, wine), but it is also commonly used for controlling the concentration of various industrial fluids (cutting coolants, glycol solutions, and flux rinsing compounds). Reichert Technical Bulletin Determining Percent Concentration of Samples. They can be mastered by ANYONE in just minutes. Zebra Glycol Refractometers have a temperature scale to read the protection rating of a ethylene and propylene glycol mixture as well as battery acids. The Glycol Refractometer offers a convenient, fast and accurate way to access the glycol concentration of engine coolants and other anti-freeze solutions. The below video demonstrates how to test your system using a refractometer. A refractometer is used to determine a concentration of a particular substance within a given solution. Antifreeze Refractometer for Glycol, Antifreeze, Coolant and Battery Acid. Stand directly under the light source for the best results. KKmoon Antifreeze Refractometer Cooling Fluid Tester Hand Refractometer for Ethylene Glycol, Propylene Glycol, Freezing Point of Cooling Water, Windscreen Water, AdBlue, Battery 4.6 out of 5 stars 28 £14.90 £ 14 . The angle between the normal ray and the refracted ray is called the angle of refraction. It requires only a few drops of liquid, and is used throughout the food, agricultural, chemical, and manufacturing industries.. How a Refractometer Works. Abbe (Laboratory) Refractometer Abbe Refractometers are bench-top meters that look similar to a microscope which provide highly precise measurements of refractive index. A Specific Gravity of 1.03 means that you either have an Ethylene Glycol solution between 25% and 30% by weight, or you have a Propylene Glycol solution between 35% and 40% by weight.
