The refractometer is very easy to use and automatically calibrates itself to water. Scale to determine the freezing point of propylene glycol-based antifreezes. If the user normally wears spectacles, it may be that the scale is sharper without them. Yes, scales are available for the Palm Abbe digital refractometer for measuring both ethylene glycol (EG) and triethylene glycol (TEG). 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). To make the conversion easier, refractometers are available with scales that are calibrated to read the desired value, in this case, percent salinity. With unmatched product and systems application knowledge, our team helps each customer do the job right the first time. This instrument requires only a few drops of fluid for glycol testing and requires no adjustment for fluid temperature. All are easily transportable for field use, simple to use, and require only an outside light source to … 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 … A refractometer is used to determine a concentration of a particular substance within a given solution. HI96832 Digital Propylene Glycol Refractometer The Hanna HI 96832 Propylene Glycol Digital Refractometers are rugged, portable, water resistant devices that utilize the measurement of refractive index to determine the percent volume and freezing point of propylene glycol based solutions. The various hand refractometers are categorized according to the type of measurement scale required. What is a refractometer? Refractometers are very easy to use, even the non-digital, analog refractometers. All glycol-based antifreezes will refract light and this property can be used to determine the concentration of treatment present. . If you want a refractometer to measure glycol (engine coolant), please contact us directly for an exchange. The angle between the normal ray and the incident ray is called the angle of incidence. Propylene glycol is used in glycol chillers and dispensing systems intended for food applications, such as beer and wine. . Let us use a hypothetical Specific Gravity of 1.03 from the test above. This article is not a substitute for review of current applicable government regulations, industry standards, or other standards specific to your business and/or activities and should not be construed as legal advice or opinion. How to use a refractometer to measure jam. +32 to -60 F Ethylene Glycol, +32 to -60 F Propylene Glycol, 0 - 70 Ethylene Glycol, 0 - 63 Propylene Glycol, 1.100 - 1.400 Electrolyte Specific Gravity (1) -50 Degrees to ... Alcohol refractometer. How to use: The Refractometer has an adjustable eyepiece. This optical refractometer is design for measuring of following characteristics:. All glycol-based antifreezes will refract light and this property can be used to determine the concentration of treatment present. The HI96832 Digital Refractometer utilizes the measurement of refractive index to determine the percent volume and freezing points of propylene glycol based solutions. Also, it is important to determine the temperature of the testing environment since temperature affects the angle of refraction. Hand refractometers are made with a variety of different scales to measure dissolved solids in solution. A 35% Inhibited Propylene Glycol to 65% water solution comes to (24.75 brix). A refractometer is a tool used for measuring concentrations of aqueous solutions.It has many applications across food, agricultural, chemical, and manufacturing industries. Both the concentration, and the likely degree of protection are indicated. b) Close and open the lens cover several times, and wait a few seconds to allow the solution to reach the refractometer’s temperature ≡ GLYCOL TESTER ∼ REFRACTOMETER: EXTREMELY EASY TO USE, PRECISION INSTRUMENT FOR MEASURING THE CONCENTRATION OF GLYCOL ANTIFREEZE. Abbe (Laboratory) Refractometer Abbe Refractometers are bench-top meters that look similar to a microscope which provide highly precise measurements of refractive index. The scale is calibrated for use at 20±2°C with the graphs provided. The HI96832 Digital Refractometer utilizes the measurement of refractive index to determine the percent volume and freezing points of propylene glycol based solutions. Since the reading will be affected by temperature changes, it is best to calibrate at the temperature of the test environment. Dynalene REF01 Rhino Duo-Chek® handheld refractometer offers an accurate, fast and easy-to-use method for testing engine coolant freeze point, glycol concentration, and battery charge condition. The Kamco refractometer 402 has been designed to give a rapid indication of the level of concentration of Freezbreaker and other glycol based antifreeze compounds. Point the instrument at … Handheld Analog Refractometer With an analog refractometer, the sample is place on a cover plate and a prism and then held to the light to view the scale inside the meter. 1994-2020, W.W. Grainger, Inc. All Rights Reserved. Below is an example of a salinity scale as seen through the eyepiece. If the user normally wears spectacles, it may be that the scale is sharper without them. Likewise, natural gas processing plants use triethylene glycol, diethylene glycol, ethylene glycol, and tetraethylene glycol to eliminate water from natural gas. Using distilled water to calibrate a refractometer: Placing 2-3 drops of distilled water on the prism. Glycol Refractometer – Do's and Don'ts. A quick and accurate way to measure the glycol concentration in a HVAC or mechanical system is through a hand-held refractometer. When the instrument is not in use, keep the cover closed to avoid scratching the prism. A quick and accurate way to measure the glycol concentration in a HVAC or mechanical system is through a hand-held refractometer. Calibration and Use of Analog Refractometers. Use CoolTrak coolant test strips (kimdon.com) to test a sample of ethylene or propylene glycol based coolants. This optical refractometer is designed for measuring coolant and antifreeze based on ethylene glycol or propylene glycol ,battery fluid condition and screenwash antifreeze (windshield washer fluid) based on ethanol as well as on isopropyl alcohol. A quick and accurate way to measure the glycol concentration in a HVAC or mechanical system is through a hand-held refractometer. Place a drop of sample on the measuring surface beneath the ViewPoint Illuminator. Antifreeze Refractometer - 3-in-1 coolant Tester for Checking Freezing Point, Concentration of Ethylene Glycol or Propylene Glycol Based Automobile Antifreeze Coolant … 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. Join Prime to save $2.10 on this item. What is the Proper Glycol to Water Percentage or Mixture? Antifreeze Tester for Measuring Freezing Point of Automobile Antifreeze and Battery Fluid Condition.
