InfraCal Soot Meter


InfraCal Soot Meter

  • Complies with ASTM Method D7686
  • One-step measurement of soot levels up to 15%
  • No Dilution or Sample Preparation
  • Rapid analysis - less than 30 seconds per sample
  • Soot Meter App 1213

Used in lubrication oil and engine testing laboratories worldwide, the InfraCal Soot Meter provides an easy-to-use ASTM approved test method for percent soot in diesel engine lubricating oils. Results correlate to the TGA (thermogravimetric analysis) reference method and FTIR methods. The Soot Meter is also ideal for truck, bus or off-highway fleets, onboard ships, construction or mining sites and power generation stations. Samples are applied scratch-resistant cubic zirconia attenuated total reflectance (ATR) sample plate and easily cleaned with a cloth or paper towel - no solvents requiring special ventilation or expensive waste disposal or difficult to clean cells. The analysis can be done by non-technical personnel with no formal training.

  • Oil testing labs - achieve comparable results to TGA or FTIR in a fraction of the time
  • Engine test labs - obtain on-the-spot assessment of the engine test progress
  • Fleet maintenance shops - check soot level to know exactly when to schedule oil changes
  • Construction or mining sites - stay operational with oil condition checks
  • On-board-ship - no need to return to port to monitor oil condition
  • Power generation stations - monitor the quality of the lubricating oil without waiting for off-site lab results
