The A1310G petroleum product colorimeter is used to determine the color of lubricating oils and other petroleum products. It corresponds to the 16 color numbers specified in GB 6540. During measurement, the sample of petroleum product to be tested is poured into the colorimetric tube, and the color number is determined by comparing it with standard color chips. It is applied in petroleum, chemical, food and other industries.

The instrument is widely used for quality inspection and production control of lubricating oils, diesel fuels, kerosene, transformer oils, hydraulic oils, petroleum products and chemical liquids.

During testing, the petroleum sample is placed into a colorimetric tube and compared with standard color glass plates under a standardized light source. The corresponding color number is determined according to the visual color comparison result.

Applicable Standard: SH/T 0168

Product Features

1. The instrument consists of a standard color disc, observation optical lens, light source and colorimetric tube.
2. It adopts a frosted milky‑shell bulb as the light source.
3. After filtering, the light source evenly illuminates the color glass chips of the standard color disc and the colorimetric tube respectively.
4. The optical eyepiece is equipped with light adjustment and focusing functions for convenient operation.

Working Principle

The A1310G petroleum colorimeter adopts the principle of visual color comparison.

The sample is illuminated by a standardized light source, and the transmitted light passes through the petroleum sample and standard color plates simultaneously. The operator compares the sample color with the standard color disk and determines the corresponding petroleum color grade.

This method is commonly used in petroleum laboratories because it provides a simple, stable and repeatable method for oil color evaluation. ASTM D1500 petroleum color testing is also based on comparing petroleum samples with standardized color references.
