Carbon Residue

Introduction

A carbon residue tester measures the amount of carbon left after evaporation and pyrolysis of petroleum products. It is widely used in refining and fuel quality testing. The system helps evaluate thermal decomposition characteristics of fuels.

Standards

ASTM D524-Standard Test Method for Ramsbottom Carbon Residue of Petroleum Products

ASTM D4530-Standard Test Method for Determination of Carbon Residue (Micro Method)

Complies with the above standards, but is not limited to them.

Features

1. Multiple sample positions process several specimens in a single run.

2. Clear display or software shows values and test stage.

3. Stirring or agitation keeps samples homogeneous during the test.

4. Method-specific design delivers repeatable, traceable results.

5. Rugged frame and corrosion-resistant bath suit daily fuel testing.

FAQ

What is the Carbon Residue mainly used for?

The Carbon Residue is used to test petroleum products, fuels, lubricants and related materials for specified properties. It supports refineries, oil laboratories, fuel inspection, transport and quality-control work.

What standards does the Carbon Residue comply with?

The instrument is designed with reference to applicable ASTM, ISO and GB/T petroleum test methods and IEC 61010 electrical safety. Procedures and reference materials must follow the named method. Compliance documentation can be provided on request.

How long is the warranty period?

The system is covered for 12 months after shipment, including the main mechanism and electrical controls. Replaceable consumables and routine service items are not part of the warranty. Faults caused by improper installation outside the manual or unauthorised modification are not covered.

Is the Carbon Residue difficult to operate?

Routine operation is straightforward and is covered in the user manual, including setup, daily use and basic maintenance. Staff with basic laboratory experience can run it after a short familiarisation. We provide remote guidance and can arrange on-site training where required.

How long does delivery usually take?

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.

Is calibration included?

Factory calibration is included, and routine verification is recommended every 6 to 12 months using suitable reference materials. Regulated sites may require more frequent checks and documented records. Calibration support and certificates can be provided on request.

Where do we get replacement parts?

The instrument uses standard, widely available consumables rather than special locked items. Replacement parts, accessories and consumables can be ordered from us against the model number. We keep common service parts in stock for prompt supply.

Are options or configurations available?

The standard model can be configured with selected accessories and operating options to suit the task. Non-standard requests are assessed before quotation so the final build is clearly defined. We confirm details before production.

Do you provide on-site installation?

The unit is delivered ready for set-up, with clear commissioning steps in the manual. We provide remote technical support during installation. For larger or regulated systems, a factory-trained engineer can attend on site on request.

What maintenance and safety points matter?

Do not use flammable samples near ignition sources, exceed temperature limits or reuse contaminated reference material. Ventilate and follow fuel-handling safety rules.
