Coal and Energy Testing

Automatic IR Sulfur Analyzer (YX-DL8802)

Determines total sulphur content in coal, coke and petroleum products using infrared spectrum absorption, with automatic sample loading.

Overview

Applicable across electrical power, coal, commerce inspection, environmental protection, metallurgy, paper making, petrochemical and earth-probe industries, and by research institutions or quality-inspection organisations, to measure total sulphur content in coal, cinder, coke, catalyst, minerals, rock and petrochemicals. Testing follows GB/T 25214-2010 ("Determination of total sulfur in coal by infrared spectroscopy").

Features

Automatic sample loading, testing and discarding until results are available, using the supplied feeding facility (Patent No. 2013200307699)
Ultra-low-draft IR cell for reliability and precision
Special gas dilution device expands the testing range without replacing the IR cell
Built-in fault-tolerant diagnostics to help identify the source of a problem
Separated feeding pipe and feeding pole for longer service life and easier maintenance
Software can link to a laboratory management system for online data upload
