The LOI test determines the minimum oxygen concentration, expressed as a volume percentage in a controlled oxygen and nitrogen gas mixture, required to sustain combustion of a vertically mounted specimen.\u003c\/p\u003e\n\u003cp\u003eBecause atmospheric air contains approximately 21% oxygen, materials with an LOI value above 21% generally tend to self-extinguish in air, while materials with an LOI below 21% can continue burning after ignition. This measurable value provides laboratories and manufacturers with a practical method for comparing the combustion behavior of plastics, polymers, rubber, electrical cables, textiles, composites, and flame-retardant materials.\u003c\/p\u003e\n\u003cp\u003eThe QualiLOI™ Series supports flammability testing in accordance with widely recognized standards, including ASTM D2863, ISO 4589-2, and NES 714.

versatile instrument for evaluating the combustion behavior and flame resistance of various materials, including plastics, rubber, fibers, foamed plastics, films, textiles, wood, and other polymeric materials. This Basic Limiting Oxygen Index (LOI) Chamber accurately determines the minimum oxygen concentration required to sustain combustion under controlled test conditions.\u003c\/p\u003e\n\u003cp\u003eDesigned for accurate, repeatable, and convenient oxygen index testing, the QualiLOI™ provides an efficient method for assessing the combustion characteristics of materials.

During testing, the specimen is exposed to a controlled flow of oxygen and nitrogen, and the oxygen concentration is adjusted to identify the minimum level required to sustain combustion.\u003c\/p\u003e\n\u003cp\u003eThe resulting oxygen index value provides an indication of a material's combustion behavior. A higher LOI value generally indicates that a material requires a greater concentration of oxygen to sustain burning, suggesting better resistance to combustion. A lower LOI value indicates that the material can sustain combustion at a lower oxygen concentration and is therefore more readily ignited.\u003c\/p\u003e\n\u003ch2\u003eRoom-Temperature and High-Temperature Oxygen Index Testing\u003c\/h2\u003e\n\u003cp\u003eThe oxygen index method can be performed using room-temperature or elevated-temperature test conditions, depending on the material and testing requirements. These methods allow laboratories to study material combustion behavior under different thermal environments and obtain useful data for polymer flammability and flame-retardancy evaluation.\u003c\/p\u003e\n\u003cp\u003eThe QualiLOI™ Limiting Oxygen Index Chamber provides a practical solution for laboratories requiring dependable LOI testing of plastics, rubber, textiles, foams, films, fibers, wood, and other combustible materials.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0786\/1859\/1543\/files\/QualiLOI-Diagram.webp?v=1786357173\" alt=\"Limiting Oxygen Index Chamber QualiLOI™\"\u003e\u003c\/p\u003e\n\u003ch2\u003eQualiLOI™ Limiting Oxygen Index Chamber Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eModern Oxygen Sensor Technology: Automatically measures and acquires the oxygen concentration percentage during Limiting Oxygen Index testing.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e0.1% Oxygen Reading Accuracy: Digital display provides clear oxygen concentration readings with an accuracy of 0.1% for precise test monitoring.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003ePrecision Gas Flow Control: A precision metering valve enables accurate adjustment of oxygen and nitrogen gas flow throughout the test.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFine Oxygen Concentration Adjustment: Supports oxygen percentage step adjustment with gas flow control accuracy of up to 0–0.2 L\/min.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAdjustable Gas Pressure: Nitrogen and air pressure-reducing valves allow the output pressure to be adjusted to 0.1 MPa.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eReplaceable External Sensor: The external electrochemical oxygen sensor provides convenient access for inspection and replacement.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHigh-Temperature Quartz Glass Cylinder: A heat-resistant quartz glass cylinder supports testing at elevated temperatures while providing clear visibility of the specimen.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAdjustable Gas Igniter: The integrated gas igniter features adjustable flame length and a gas shutoff function for convenient and controlled ignition.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eInternational Test Standards: Designed for testing requirements associated with ASTM D2863, ISO 4589-2, and NES 714 standards.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eQualiLOI™ Limiting Oxygen Index Chamber Technical Specifications:\u003c\/h2\u003e\n\u003ctable class=\"table\" border=\"1\" cellpadding=\"1\" cellspacing=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"text-align-center\"\u003e\u003cstrong\u003eDimension\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"text-align-center\"\u003e370 mm (W) x 300 mm (D) x 480 mm (H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"text-align-center\"\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"text-align-center\"\u003e8KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"text-align-center\"\u003e\u003cstrong\u003ePower Supply\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"text-align-center\"\u003e220V, 10A (110V available upon request)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"text-align-center\"\u003e\u003cstrong\u003eAmbient Temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"text-align-center\"\u003e10°C to 35°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"text-align-center\"\u003e\u003cstrong\u003eInstallation Space\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"text-align-center\"\u003ePlace in a fume hood\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"text-align-center\"\u003e\u003cstrong\u003eGas Required\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"text-align-center\"\u003eOxygen and Nitrogen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cdiv id=\"gtx-trans\"\u003e\n\u003cdiv class=\"gtx-trans-icon\"\u003e \u003c\/div\u003e\n\u003c\/div\u003e","brand":"Qualitest USA LC","offers":[{"title":"Default Title","offer_id":52810433528119,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/1859\/1543\/files\/limiting-oxygen-index-chamber-qualiloitm1296828669.webp?v=1786357235"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/1859\/1543\/collections\/loi-limiting-oxygen-index-chamber1990678704.webp?v=1786356616","url":"https:\/\/qualitest.us\/ar\/collections\/loi-limiting-oxygen-index-chamber.oembed","provider":"Qualitest USA LC","version":"1.0","type":"link"}
