Model: K581 X-ray Fluorescence Sulfur-in-Oil Analyzer

Measure the mass(%) of total sulfur in crude petroleum, petroleum, heavy oil, diesel oil, gasoline and naphtha; to test total sulfur content in products of coal chemical industry, for instance primary benzene; to test total sulfur or sulfide in other liquids or solid power samples.

Conforms to ASTM D4294 and related specifications.


Adopting method of Fluorescence Intensity Ratio Analysis, it can analyze various kinds of samples, wide testing range, rapid analyzing, less sample quantity consumption;

Electro-mechanical integration design, microprocessor control, LCD display, user-friendly interface;

Self-diagnostic function. It can judge itself working state and electric parameters. Temperature and pressure can be corrected automatically, also ratio of carbon and hydrogen (C/H) can be corrected;

Adopting disposable Mylar film sample vessel, it can avoid cross contamination;

Sample vessel is made by multifunctional press, rapid and convenient. Sample serial number, S%(m/m) and date can be recorded;

Sample holder precisely positioned; it automatically moves out from inside of instrument when testing sample; Easy for loading sample and replacing anti-leakage parts; also to avoid contamination to detection system;

Large test data storage. Analysis result and calibration curve parameter can be checked at any time;

Built-in thermal printer;

RS232 serial port;

Sale and reliable X-Ray protection measure.
