An inhibited propylene glycol such as “DowFrost” is best. As different types of base oil also vary in terms of their refractive index, this value is also helpful for identifying mixtures of different oil types, among other things. 2. By Fax: (617) 254-2713. 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. Create a chart that you can plot points on as information is developed to correlate the readings from the Refractometer to “Actual Percent Concentration” for your solution. We inspect every mixture using a refractometer, our technicians then determine the freezing point of each batch and (if needed) adjustments are then made to achieve the desired percentage.

Traditional test strips can be difficult to read and are not always accurate. However, the mixed solution of water-glycol will be thicker, heavier, than the water alone was. RF40: Portable Battery Coolant/Glycol Refractometer with ATC (°F) Measures the freezing point of coolants and concentration of Ethylene/Propylene Glycol. These questions ultimately affect the mixture ratio of the glycol. – The Glycol Refractometer is designed for testing for concentration of glycols. Our manufacturer inspects every mixture using a refractometer, glycol technicians then determine the freezing point of each batch and (if needed) adjustments are then made to achieve the desired percentage. Coolant Freezing Point Determines the effectiveness of ethylene glycol and propylene glycol coolants; Clinical: Measures Serum albumen and urine-specific gravity (e.g. Every order of propylene and ethylene glycol goes through a rigorous amount of testing before being shipped. K 18-460. Refractometer Shop is committed to providing certified, quality products from a brand you can trust. Measure the solution using a glycol refractometer. ... (see chart). Hercules 35290 - Refractometer - Using anti-freeze within the recommended levels of concentration ensures efficiency of heat transfer.
