Import Digital Display Oxygen Index Apparatus — Buy in wholesale FOB from Supplier in China

The Digital Display Oxygen Index Apparatus supplied by Zonsky Instrument Co, Ltd is designed to evaluate the oxygen index of plastics, rubber, paper, building materials, textiles, wood and other polymer products. Its combustion chamber incorporates a quartz glass tube with an inner diameter of 100 mm and a height of 450 mm, providing a clear visual field for flame propagation. The instrument can regulate oxygen concentration from 10 % up to 60 % to meet the requirements of GB/T 5454‑97, GB/T 2406‑2008 and GB/T 10707‑2008 testing methods. Pressure monitoring is achieved through three dedicated meters displaying oxygen output pressure, nitrogen output pressure and mixed‑gas output pressure respectively.

The quartz glass tube offers high thermal resistance and chemical inertness, a material choice typical for laboratory combustion chambers. Sample clips are sized at 140 mm × 38 mm, a dimension commonly used to hold standard test specimens across the industry. The manual igniter is engineered for safe and reliable flame initiation, aligning with the typical safety standards of combustion testing equipment. Typical laboratory instruments of this class operate on a 220 V AC power supply and provide a measurement accuracy of ±0.5 % oxygen index, although the exact figure for this unit is not listed.

Primary users include material testing laboratories, research institutes and manufacturers that need to certify flame‑retardant performance for regulatory compliance. Importers usually request confirmation of certification to the referenced GB/T standards, as well as details on minimum order quantity, lead time and preferred Incoterms before finalising a contract. Zonsky’s listing does not disclose MOQ, pricing or shipping conditions, so prospective buyers should contact the supplier directly to negotiate bulk trade terms.
