I. Introduction:
The LAB135 type Saybolt colorimeter is used to determine the color
of refined liquid petroleum products, such as undyed automotive
gasoline, aviation gasoline, jet fuel, naphtha, kerosene, and
medicinal white oil. The Saybolt color refers to the numerical
value of the liquid column height that is closest to one of the
three standard color plates when observed through the sample liquid
column for comparison with the standard color plates. The Saybolt
color numbers are specified as ranging from -16 (the darkest) to
+30 (the lightest). The Saybolt color test (Saybolt Color) is used
for quality control and product identification of refined products
with an ASTM color of 0.5 or lower.
The determination of petroleum product color is mainly used in the
control process of oil production. Since color is an important
quality characteristic of petroleum products and is also a feature
that users can easily observe. In some cases, color can reflect the
degree of refinement of the product. For petroleum products with a
known color range, if the color exceeds this range, it may be
contaminated.
II.Main Features
1.Complies with ASTM D156 and relevant international standards for
measuring the color of liquid petroleum products.
2.This Saybolt colorimeter is equipped with an optical system
originally imported from Europe.
3.Certified by the National Standard Testing of the Scientific
Metrology Institute, capable of issuing authoritative test reports.
4.Features an aviation-grade aluminum alloy structure for increased
stability and durability.
5.Abandons the rough structure of traditional casting processes,
utilizing advanced and precise CNC machining.
6.Rigorous quality control ensures long-lasting durability,
offering a quality guarantee that exceeds the industry's similar
products by three times the lifespan.
7.Easy and flexible to operate.
8.Provides accurate, fast, and clear test data.
