X-ray wavelength dispersive sulfur analyzer ASW-3
X-ray wavelength dispersive sulphur analyser ASW-3 is used for the measurement of mass concentration of the sulphur in un-leaded gasoline, diesel oil, crude oil, kerosene, petroleum residues, lubricating oil, hydraulic oil, jet engine fuel and other types of cutter oil.
Analyser ASW-3 allows to measure mass concentration of the sulphur in vacuumized measurement chamber mode, as well as in helium purging mode. For this purpose the instrument is equipped with the set of tooling for the connection to helium station.
