Technicians use it to quickly determine whether a coolant mixture provides adequate protection for the operating environment. The instrument works by measuring how light refracts through a fluid sample, translating that reading into a freeze-protection temperature value. It is a compact, handheld tool suited for HVAC technicians, automotive service professionals, and fleet maintenance crews who need fast, reliable coolant condition checks in the field or shop.\u003c\/p\u003e\u003cp\u003eThis refractometer is used wherever antifreeze or coolant mixtures need to be verified before or after service. Typical applications include checking radiator and hydronic heating system coolant, verifying glycol concentration in chilled-water and heat-pump loop systems, and confirming freeze protection in equipment exposed to low ambient temperatures. It is well suited for residential and light commercial HVAC work as well as general mechanical maintenance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasures antifreeze and coolant concentration for freeze-point protection verification\u003c\/li\u003e\n\u003cli\u003eHandheld, compact form factor for field and shop use\u003c\/li\u003e\n\u003cli\u003eOptical refractometer design requires no batteries or power source\u003c\/li\u003e\n\u003cli\u003eSingle-unit package quantity for individual technician use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose antifreeze and coolant tester compatible with standard ethylene glycol and propylene glycol-based coolant mixtures used in HVAC and mechanical systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo installation is required for this handheld instrument. Before use, ensure the prism surface is clean and dry, then place a small fluid sample on the prism and close the cover plate before reading. Calibrate the refractometer periodically using distilled water per the manufacturer instructions. Keep the optical lens clean and protected from impact to maintain reading accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefractometer Type\u003c\/strong\u003e: Antifreeze and Coolant Tester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41113736\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KP74477\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699758072114,"sku":"KP74477","price":43.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75ef1dea3edb8ad79e242b0d4d2903c1.jpg?v=1788380459","url":"https:\/\/voomisupply.com\/products\/value-collection-kp74477-antifreeze-coolant-refractometer","provider":"Voomi Supply","version":"1.0","type":"link"}
