{"product_id":"resol-refraktometer-set","title":"Resol Refractometer Set","description":"\u003cp\u003eWith 1-2 drops of the test liquid, the hand refractometer determines the cloud point of water-propylene glycol, water-ethylene glycol, and water-ethanol mixtures, and the refractive index of any liquids. The Cloud Point: An antifreeze mixture, when cooled down to the freezing point, will not instantly freeze at a specific temperature, but rather the freezing process is continuous – meaning: the mixture forms the first ice crystals at a certain temperature (=cloud point), and then an increasingly viscous mass is created, which is then completely frozen at a correspondingly lower temperature (=pour point). The frost point used in most refractometers is in the range where the antifreeze liquid has already become a viscous mass (pumpable ice slurry) and is therefore no longer suitable for applications in the solar or heat pump sector.\u003c\/p\u003e","brand":"Resol GmbH","offers":[{"title":"Default Title","offer_id":54271215829333,"sku":"28000600","price":121.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/1247\/2405\/files\/Refraktometer2015_445x445_68a7fe09-6cb1-4321-85d4-0070c8573186.jpg?v=1782999545","url":"https:\/\/wohnungstechnik.de\/en\/products\/resol-refraktometer-set","provider":"Wohnungstechnik.de","version":"1.0","type":"link"}
