– Standard Illuminant, Accurate Color Matching for Oil Grading
Introduction:
Color is a key quality indicator for many petroleum products. The DFYF-169 Colorimeter is specifically designed to determine the color of lubricating oils, diesel fuels, fuel oils, and other petroleum derivatives in full compliance with international standards. With a standard illuminant, sealed optical path, and easy-to-use filter changer, it delivers reliable and reproducible color grading.
Standards Compliant:
GB/T 6540, SH/T 0168, ASTM D1500
Technical Specifications:
Parameter | Value |
Power Supply | AC220V, 50Hz |
Power Consumption | 110W |
Number of Test Holes | 2 |
Key Performance Features:
1. Standard Illuminant
The instrument uses an internationally accepted light source, providing uniform and stable illumination without flicker or shadow – ensuring consistent viewing conditions and minimizing visual errors.
2. High-Precision Color Reference Filters
Equipped with standard-compliant color slides (glass filters) offering accurate transmittance and minimal deviation, allowing clear identification of color numbers.
3. Sealed Optical Path
The light path is fully enclosed, effectively blocking stray light from the environment. This ensures that every measurement is performed under stable, controlled lighting for excellent repeatability.
4. Easy Handwheel Filter Changer
A handwheel mechanism allows smooth and rapid switching between different color filters. Simple to operate, it improves testing efficiency.
Key Advantages:
Meets multiple standards (GB/T 6540, SH/T 0168, ASTM D1500) – results are comparable across regions
Compact 2-hole design for routine laboratory use
Low power consumption (only 110W) – energy saving
Suitable for refineries, quality control labs, and oil trading inspection
Applications:
Color determination of lubricating oils, diesel, fuel oils, transformer oils
In-process quality control and product release testing
Compliance checks for import/export petroleum products
Conclusion:
The DFYF-169 combines a standard illuminant, precision color filters, a stray-light-proof optical path, and user-friendly operation – making petroleum color testing simple, accurate, and traceable.
