Portable IR Analyser Provides ASTM Method for On-site Soot Measurement of Diesel Engine Lube Oils

摘要

The InfraCal Soot Meter, from Wilks provides users with an approved ASTM test method to measure the percent level of soot in diesel engine lubricating oil. ASTM Method D7686-2011 entitled "Test Method for Field-Based Condition Monitoring of Soot in In-Service Lubricants Using a Fixed-Filter Infrared (IR) instrument" allows for easy, on-site measurements in less than 30 seconds without sample preparation using a filter-based infrared (IR) analyser. With the InfraCal Soot Meter, rapid, on-site measurement of soot concentration levels in diesel engine oils at levels as high as 12 - 15% takes less than 30 seconds. This compact, factory-calibrated pushbutton analyser provides direct readout of the percent of soot in diesel engine lubricating oils without sample preparation, dilution, or solvents and messy transmission cells to clean.
