The SGS laboratory in Naperville, Illinois now offers diesel fuel quality testing for use in mission-critical back-up stand-by diesel-fuel power generators. Located in the greater Chicago area, the laboratory also offers expert oil condition monitoring services. 
Stored diesel fuel must be able to support mission-critical back-up power generation at power plants, hospitals, airports, and other institutions and businesses. New fuel deliveries may not meet quality standards, and on-site stored fuels can age and degrade over time. Sampling and testing stored diesel fuel helps ensure back-up generator readiness and maintenance.

  • Distillation, D86
  • Flash Point, D93
  • Pour Point, D97
  • API Gravity, D287
