- Model DT100DL - In-Service Engine Oils with Blotter Spot Method


The requirement for on-line machinery and oil condition monitoring is becoming evermore apparent as maintenance costs increase and production capacity and equipment performance are maximized. One of the primary functions of a lubricant is to preserve the cleanliness of a combustion engine's mechanical parts. The cleanliness of the mechanical parts is facilitated by 'detergency' and 'dispersancy' (DD) additives in the engine oil.

The dispersancy is the property that allows the oil to suspend and carry away 'pollutants' of diverse sources such as soot from combustion, metallic particles from wear, corrosion of mechanical parts, and insoluble products resulting from the ageing of the oil, etc. Dispersant additives in oil prevent agglomeration and sludge formation by dispersing contaminants. With proper formulated oil, the soot will remain homogeneously suspended up to high concentration levels. When soot load reaches a critical limit for current condition of the oil, a sudden loss of dispersancy leads to rapid agglomeration and deposition of soot onto machine surfaces. Contaminants like water and/or glycol can quickly knock out dispersancy performance without an increase in soot load. Diesel engine condition monitoring requires increased focus upon measuring both soot concentration and dispersancy performance. Unlike measuring soot concentration where numerous options exist, measuring soot content and dispersancy performance is a real challenge to the oil analyst.

The DT100DL operates according to ASTM D7899. The instrument simultaneously measures soot and dispersancy. The results reported are combining soot content and dispersancy performance.

The DT100 takes a spot image with a built-in digital camera. In seconds, the software scans and analyzes all the different areas of the oil spot and automatically calculates the quantitative quality parameters of a motor oil in service. The DT100 has been designed to satisfy needs of OCM laboratories. It is an easy-to-use and robust analyzer equipped with enhanced quality and communication features. The spot images can be stored on USB storage devices and sent to local networks (LIMS) with an Ethernet interface. Versatile communication protocol is configurable for the specific requirements of each laboratory. The DT100 provides fully traceable electronic data storage eliminating the need for paper archiving. A laboratory technician can perform on-site calibration in minutes using a standard calibration tool supplied with the instrument. The DT100 complies with modern QA/QS laboratory practices.
