Instrument Overview Technical Parameters Performance characteristics


  This instrument can accurately measure the elemental composition and concentration of trace metal abrasive particles and their additives in oil samples, in order to grasp the wear status, lubrication status, and contamination status of lubricating oil of the equipment. Through statistical analysis and trend analysis of historical data (detection results and equipment maintenance records), it can comprehensively grasp the wear trend and changes in lubrication status of the equipment. The execution standard and detection precision of the instrument shall meet the ASTM D6595 method standard (the standard method for determining wear metals and pollutants in lubricating oil or Hydraulic fluid by rotating disc electrode Atomic emission spectroscopy). This instrument is designed and optimized for performance using the latest CCD optical system and the durable and reliable Rotating Disk Electrode Technology (RDE). Quantitative analysis of small particles dissolved or suspended in oil is easy to operate, highly reliable, and durable. It can quickly detect the content of metal abrasive particles, pollutants, and additive elements in lubricating oil, making it suitable for commercial and military oil monitoring laboratories.
