KZDL-4C fast intelligent sulfur analyzer

KZDL-4C fast intelligent sulfur analyzer

Adopting standards:

GB/T214-2007 "Determination of Total Sulfur in Coal", GB/T483-2007 "General Provisions for Coal Analysis Experimental Methods", GB/T387 "Determination of Sulfur Content in Dark Petroleum Products - Tube Furnace Method"

Scope of application:

Suitable for the determination of total sulfur in coal, coke, petroleum and other substances in power, coal mining, metallurgy, chemical, cement geological exploration, scientific research institutions and other departments.

Performance characteristics:

Lenovo computers and printers must be equipped to operate the instrument;

Automatic control of the heating process of the high-temperature electric furnace;

■ Automatic zero calibration of instrument system;

Automatically determine the endpoint of the testing process and exit in a timely manner;

The instrument can automatically maintain up to 100 times of test data, automatically update, and prevent data loss during power outages;

Technical parameters:

Test principle: Coulombic titration method

■ Sample quantity: 1

■ Dimensions: 680mm × 480mm × 430mm

Net weight of the instrument: 40kg

(The following technical parameters are not only available for this instrument, but also for other types of sulfur analyzers in our company.)

Test principle: Coulombic titration method

■ Sulfur resolution: 0.001% (higher than other peers' 0.01%)

■ Sulfur measurement range: 0.1% to 40% (if exceeding the range, please contact special models by phone)

■ Sample weight: 50.0mg (input range 0.1 ㎎~99.9 ㎎) Ultra high sulfur content samples can be weighed less, while ultra-low sulfur content samples can be weighed more for easy analysis of other substances

Test time: 4-8 minutes (automatic determination of titration endpoint, specific time depends on sample type and weight)

Test temperature: 1150 ℃ (coal coke) and 920 ℃ (oil). The temperature control range is 400-1200 ℃, which is convenient for other analyses

Temperature control accuracy ± 2 ℃.

Precision: Complies with GB/T214-2007

Accuracy: Within the allowable error range of the standard sample, and better than the national standard
