Portable IR Analyser Measures Soot Levels in Diesel Engine Oils in Under 30 Seconds Without Sample Preparation

摘要

Extended drain times, combined with stringent emission requirements, make it important to routinely check the soot levels in diesel engine lubricating oil. Rapid, on-site field measurement of soot concentration levels in diesel engine oils at levels as high as 1 2 - 1 5% takes less than 30 seconds with the InfraCal Soot Meter available from Wilks Enterprise (USA). This compact, pushbutton analyser provides direct readout of the percent of suspended carbon (soot) in diesel engine lubricating oils without sample preparation, dilution, or solvents and messy transmission cells to clean. Currently, an ASTM Method covering the InfraCal Soot Meter entitled, "Condition Monitoring of Soot in In-Service Petroleum and Hydrocarbon-Based Lubricants Using a Fixed-Filter Infrared (IR) Instrument", is pending.
