Import Astm D1500 Oil Color Meter Spectrophotometer — Buy in wholesale FOB from Supplier in China

This petroleum products chroma meter is designed for colour determination of lubricants and other petroleum products according to SH/T0168-92, the Chinese petrochemical industry standard equivalent to colour measurement by comparison methods. The instrument correlates colour numbers to ASTM D1500, GB/T6540, and ISO colour scales, enabling cross-standard reporting for international trade and quality control. The source description specifies an optical system using US YBS refraction angle technology, a Canon colour wheel, belt drive transmission, and independent zoom magnification, though no numerical measurement ranges, repeatability data, or resolution specifications are provided in the listing.

The colour comparison method follows the principle of injecting a test sample into a colour tube and matching against standard colour films, rather than spectrophotometric measurement of full spectral data. Standard ASTM D1500 colour ranges from 0.5 to 8.0, with precision instruments achieving repeatability of ±0.1 colour units and reproducibility of ±0.2 units under controlled conditions. The Canon colour wheel mentioned is a physical disc with glass standard colour filters, requiring periodic verification against certified reference materials. The YBS optical system with automatic refraction angle adjustment eliminates manual calibration steps, though the specific angular resolution and wavelength range are not stated. Belt drive transmission for colour number conversion suggests mechanical indexing of the colour wheel rather than electronic selection, which may influence long-term maintenance intervals.

Target buyers include petroleum refineries, lubricant blending plants, independent testing laboratories, and quality control departments in fuel distribution networks. The instrument serves applications in incoming raw material inspection, finished product certification, and regulatory compliance monitoring for products traded against ASTM D1500 or GB/T6540 specifications. Changsha Friend Experimental Analysis Instrument Co., Ltd. is located in Changsha, Hunan Province, with the listed address at 3F/8, No. 627 Lugu Road within the Longsea Group complex. Buyers should confirm whether the quoted instrument includes the complete set of standard colour tubes, spare lamps, and certified colour standards, or if these are priced separately. The listing does not state MOQ, lead time, warranty terms, or calibration service availability, all of which require direct supplier confirmation.

Changsha Friend Experimental Analysis Instrument Co., Ltd is located at 3F/8, No. 627 Lugu Road, Longsea Group, Changsha, Hunan Province, China, postal code 410000. The supplier holds a trust tier classification of "harbor" on the platform, with a recorded response rate of 0.00% and zero average response hours. These metrics indicate no verified communication history through the platform's enquiry system, so buyers should initiate contact through direct channels and document all correspondence for their procurement records.

The company specialises in experimental analysis instruments for the petroleum industry, as indicated by its name and the product offering. The source description and supplier profile contain no information about year of establishment, registered capital, factory floor area, number of employees, annual revenue, export licence status, or named domestic or international clients. The address places the company within a commercial building rather than a dedicated industrial park, suggesting possible trading or light assembly operations rather than full manufacturing. Buyers should request business licence verification, scope of business confirmation, and details of in-house versus outsourced production for critical components such as the optical assembly and colour wheel.
