ASTM Oil Color Visual Colorimeter

2000A series of visual colorimeters, each model has a separate chromaticity standard and corresponding application field. The main color codes in this series includePt-Co，Gardner，ASTM，EBCWait. Insert the corresponding color chart into the colorimeter and perform color grading by visual comparison.

AF509/C——ASTMColor code

LovibondAF509/CIt is a fuel specific instrument used for followingASTMVisual color grading of fuel oil within a limited range of color codes. through the use ofAF509/CConduct chromaticity measurement to ensure that the fuel used meets the standards, in order to prevent damage and maintenance costs caused by inferior fuel. The operator loads the sample into33mmIn the glass sample pool, the color of the sample can be compared withASTMCompare the color plates directly until they match, and quickly determine whether they are qualified.

ASTMColor Code Introduction

ASTMD1500Defined byASTMColor code is the most commonly used standard for detecting the chromaticity of petroleum. support16The glass filter with calibrated light projection rate and chromaticity is embedded in two chromaticity disks0.5A chromaticity unit with intervals from0.5(Shallow) Increase to8.0(The deepest). Lubricating oil, thermal oil, diesel, mineral insulation oil, and solid paraffin can all be measured using this standard method.
