This instrument is designed and manufactured in accordance with GB/T387 “Test Method for Sulfur Content in Petroleum Products” (Tube Furnace Method) and ASTM D1551. It is suitable for determining the sulfur content in petroleum products such as lubricating oils, heavy petroleum products, crude oils, petroleum cokes, paraffins, and sulfur-containing additives.

Main features:

1. Composed of a horizontal tube furnace system, a digital display temperature control system, a motor drive control system, an air purification flow regulation system, etc.

2. The operation of the servo motor is automatically controlled by a single-chip microcomputer, and it has the functions of manual fast forward, fast backward, measurement, and stop.

3. Two parallel-installed quartz tubes with ground straight pipes can test two samples at the same time, and two results can be obtained in parallel at one time.

4. Controlled by a single-chip microcomputer program, it has the advantages of a compact shape, reasonable design, and convenient use.
