I.Purpose and scope of application

This instrument is designed and manufactured in accordance with the requirements specified in the Nation Standard GB/T 17144 and ASTM D4530 "Determination of Carbon Residue in Petroleum Products (Micro Method)", and is used for the determination of residual carbon in petroleum products.

The measuring range of this instrument for residual carbon is: 0.10% (m/m) to 30.0% (m/m). For products held with carbon residue exceeding 0.10% (m/m), the results are equivalent to the measurement results of the Kang's carbon residue method (GB/T 268).

This instrument is also suitable for petroleum products whose carbon residue value is lower than 0.10% (m/m) and consists of distillate oil, but should first use gb/6536 method to prepare 10% (V/V) distillation residue, and then use This instrument measures.

III. Working principle overview

This instrument uses a single-chip microcomputer control system, according to a pre-set program, directing the coordinated operation of various components. This machine can receive balance data; it can automatically control the progress of the experiment according to standard requirements: increase the temperature at a constant rate at a rate of 10℃～15℃ and finally keep the temperature constant within the range of 500℃±2℃; automatically adjust the nitrogen flow rate as required ; Automatically perform various actions in accordance with the time sequence, and each step will have a different sound to remind the user of the progress of the experiment. The system collects experimental data, automatically calculates the experimental results, and saves and prints the data according to user requirements. This instrument is designed with an all-Chinese interface, and there are current operation prompts at the bottom of each interface. The user does not even need to read the manual, as long as the operation is carried out according to the current prompts.
