Refractometers are very easy to use, even the non-digital, analog refractometers. Can I use it? 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. As an example, refractive light can be used to determine the sodium chloride (NaCl) concentration/salinity in a brine solution. No order mins. If this is not possible, correction charts may be used. Stand outside in bright sunlight when conditions allow it. Both the concentration, and the likely degree of protection are indicated. A hydrometer is a tool used to measure specific gravity. Each compound has a specific index of refraction. . Place a drop of sample on the measuring surface beneath the ViewPoint Illuminator. Just place a few drops of fluid on the prism and hold the unit up to a light source. The … THE PRODUCTS YOU NEED, 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 … Read the scale value at the point where the dark and light portions meet. Point the instrument at a light source when taking the reading. This easy-to-use optical instrument provides a no-mess, instant result that is impossible to achieve using … Be sure the instrument is clean and dry before use Use enough fluid to cover the entire measuring prism If the water has particles in it you won’t be able to accurately calibrate the refractometer. What is a refractometer? Continuous measurement of the glycol concentration with the inline refractometer ensures automatic, active monitoring of the concentration Such retrofits require converting the mineral oil to a polyolester (POE) or polyalkylene glycol (PAG), an alkylbenzene lubricant (Zerol®) to a POE, or a mineral oil to an alkylbenzene. use. Certain GM and European vehicle makes use different colors to distinguish their antifreeze types. Which is it? Take a look at our complete lab supply selection. Price $131.00. Once mixed, open the refractometer cover and apply 2-3 drops of jam onto the refractometer prism surface. What is a refractometer? Get it as soon as Thu, Dec 31. 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. The scale is calibrated for use at 20±2°C with the graphs provided. Freezbreaker is a propylene glycol based WHEN YOU NEED THEM. Propylene glycol is used in glycol chillers and dispensing systems intended for food applications, such as beer and wine. What is the Proper Glycol to Water Percentage or Mixture? G&D Chillers recommends a 35% Inhibited Propylene Glycol to 65% water (24.75 brix). 90 A handheld refractometer is easy to use. When the measurement is complete, wipe the prism with a soft lens tissue. SIGN UP FOR EMAILGet more great content in your inbox. Here are a few do’s and don’ts for the proper use of this instrument. When light enters a liquid it changes direction; this is called refraction. The angle between the normal ray and the refracted ray is called the angle of refraction. All glycol-based antifreezes will refract light and this property can be used to determine the concentration of treatment present. Antifreeze Tester for Measuring Freezing Point of Automobile Antifreeze and Battery Fluid Condition. Stand directly under the light source for the best results. $20.99 $ 20. Manual methods like portable optical refractometers and ABBE optical refractometer are widely used for the determination of refractive index and related values, e.g. This percentage is the concentration of NaCl in the brine solution. b) Close and open the lens cover several times, and wait a few seconds to allow the solution to reach the refractometer’s temperature Determining Percent Concentration of Samples, Disinfecting the Workplace After COVID-19 Exposure. With unmatched product and systems application knowledge, our team helps each customer do the job right the first time. The angle of refraction is dependent on the composition of the media and on the temperature. Let us use a hypothetical Specific Gravity of 1.03 from the test above. 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. Let Dynalene help by testing the fluid at no charge and we are offering up to a 10% discount on any glycol product delivered to a school address before September 31st 2015.
