Introduction
A Saybolt colorimeter is an instrument used to measure the color of refined petroleum products, such as gasoline, kerosene, diesel fuel, lubricating oils, and waxes, using the Saybolt color scale, and it is used in the petroleum refining, fuel, and lubricant industries for quality control. The Saybolt color scale is a scale of color for light petroleum products, ranging from +30 for the lightest products to -16 for darker products, and the color is measured by comparing the sample with standard colored glass discs or by measuring the light transmitted through the sample; the Saybolt colorimeter consists of a light source, a sample tube or cell, a color standard, and a viewing system, and in operation, the sample is placed in the tube, and the light transmitted through the sample is compared with the standard, and the Saybolt color number is determined, following standardized methods, such as ASTM D156; the Saybolt colorimeter provides a rapid and objective measurement of the color, which indicates the quality and the degree of refinement of the petroleum product, and it is used for the control of the color of products such as gasoline and kerosene. Saybolt colorimeters are used in petroleum refineries for quality control of refined products, in laboratories for testing fuels and lubricants, in the petrochemical industry, for compliance with specifications, for research, and for many other applications, and they are available as benchtop instruments with features such as digital displays and data management. With their color measurement of petroleum products, Saybolt colorimeters are essential for petroleum quality control.

FAQ
Q1: What scenarios is this colorimeter used for?
A: It measures the Saybolt color of light petroleum products by visual comparison against standards for fuel and oil QC.
Q2: What standards does it comply with?
A: It follows ASTM D156 for Saybolt color, related ISO and GB/T standards, with standards and cells verified. The relevant parameters are verified during final inspection before shipment, and compliance documentation or test reports can be provided on request for your quality records.
Q3: What is the warranty?
A: The colorimeter carries a 12 to 24 month warranty covering the apparatus. Standards and cells are consumables. Damage from misuse is excluded.
Q4: Is it hard to operate?
A: Operation is simple after training: fill the cell, compare and read. We provide a manual and guidance.
Q5: What is the lead time?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is calibration required?
A: We recommend verification against traceable standards at regular intervals, typically every 6 to 12 months, and keeping calibration records for audit purposes. The manual describes the procedure, and reference standards are available from us. Accredited third-party calibration can also be arranged on request.
Q7: Are consumables universal?
A: Color standards are certified and method-specific, while cells are standard. Ongoing cost includes standards.
Q8: Can it be customized?
A: Yes, several configurations are available. Options include automatic versus visual measurement and sample capacity. We can discuss further custom requirements, confirm feasibility and advise any effect on the schedule before the order is confirmed.
Q9: Is installation included?
A: No installation is required for this unit. It is ready to run after a simple power connection and the leveling steps shown in the manual. We supply a detailed operation guide and online setup videos, and on-site commissioning can be arranged separately if your facility requires it.
Q10: What samples are compatible?
A: It handles clear light petroleum products within the method. It is not for dark products requiring ASTM D1500, turbid samples, or non-petroleum liquids.
