Through its subsidiaries, they mainly operate in four business segments: oil, chemical, lubricant and R&D. In mid-2012 SK Innovation did a demo installation of analyzers from NEO Monitors for measuring oxygen. The laser technology used in the solutions from NEO was new to the Korean market. After a 6 month demo period SK Innovation evaluated the test unit carefully based on many parameters. The result was very positive and proved that solutions from NEO Monitors were superior in the competition.
