SOLA II Sulfur Online Analyzer

• Full scale measurement range are from 0 to 5 ppm/wt to 0 to 9000 ppm/wt detection limits as low as 0.25 ppm
• Automatic stream switching is also available for dual-stream or quad-stream applications
• Sample combustion uses air only, no pure oxygen is required
• Longer life and better low detectable limits than non-pulsed UV systems
• Low consumables
• Low maintenance
• Continuous sample injection
• Easy operation
• Meets low sulfur in fuels measurement needs now and in the future

Analog Outputs: 4-20mÅ DC for each stream (optional)

Alarm Outputs:  One global dry contact triggered by one or more of the following:

Low sample flow alarm (optional); Low detector flow alarm; Oven/Pyrolyzer temperature fault; Injection valve fault; Purge failure; Calibration fault; Detector temperature fault; Detector lamp voltage fault

One out of service dry contact triggered by: Analyzer in calibration; Suspension of analyzer

Analog Inputs:  Optional 4-20mÅ DC inputs from density meter for automatic density compensation of ppm S (w/w); Optional 4-20mÅ DC input from sample flowmeter

Digital Data Communications:
