Antifreeze Digital Refractometer PCE-DRA 1 Ethylene Glycol / Propylene Glycol. 008985665, 008985632, 008985624 are registered trademarks and PCE Instruments and other names of PCE products referenced herein are trademarks or registered trademarks of PCE Holding GmbH. 4.7 out of 5 stars 186. Propylene Glycol Freezing and Boiling Point Chart (DOWFROST and DOWFROST HD) Ethylene Glycol Freezing and Boiling Point Chart (DOWTHERM SR-1) Upon completing your glycol testing, you may need to increase your system's concentration using glycol addition. The system can become clogged with dirt, surfaces can overheat, various types of corrosion, leaks and many other problems can occur – this is the result of using the antifreeze or coolant with unnecessary additives and bubbles. - Small liquid sample size of just 4 to 5 drops 4.6 out of 5 stars 28. £49.97 £ 49. PCE-DRA 1 is a handheld digital antifreeze refractometer used to determine the percentage or content and freezing point of propylene glycol- and ethylene glycol-based solutions. 1 sec. This Refractometer is mainly used to measure the ethylene glycol and propylene glycol concentration of the antifreeze using your cars, your solar plant, heat pumps, the freezer the pads of windscreen washer that determine heating system or other machines or systems With this glycol, the freezing point of the cooling water drops to around -10 °C to -40 °C at a proportion of 20 to 50 percent, depending on the manufacturer. Propylene glycol is used in glycol chillers and dispensing systems intended for food applications, such as beer and wine. Dieses Gerät misst den Anteil des Frostschutzmittels und Einfrieren von Glasreiniger, Blei-Säure-Batterie-Elektrolyt. Bitte versuchen Sie es erneut. Propylene Glycol and Ethylene Glycol are often mixed in many different dilution ratios and solution concentration is directly related to freeze point. Wasser über die gesamte Oberfläche des Prismas breitet ohne Luftblasen oder trockene Stelle. This waterproof IP65-rated digital refractometer features automatic temperature compensation (ATC) from +10 ... +40 °C / +50 ... +104 °F, as well as a large, easy-to-read LCD that shows both the measured value and the temperature.
