The Grease Thief® extracts representative grease samples from critical machinery for subsequent analysis and condition based maintenance. Compliant with the ASTM D7718 standard for sampling in-service greases, the technology is seen in recommended practices for applications in wind, powerplants, biomedical facility equipment, mining, steel making and general manufacturing. The Grease Thief® enables a full test slate with just 1 gram of sample.

PanAn Testing & Engineering Co.,Ltd. was founded and established in 1998 by its current Chairman, David G. Zhou. PanAn has established itself as the premier provider of sales, distribution, and engineering support for high quality laboratory equipment to the Chinese petrochemical industry from manufacturers such as Cannon, Instrument Company, D-2, AD-Systems, Falex, Canty, PCS, Hydramotion, Thermaprobe, and Zematra.

“We are excited to be working with the PanAn organization and David Zhou, leaders in the important Chinese market for petroleum products testing. By adding the Grease Thief® line of sampling and analysis products, they are opening the door for Chinese laboratories and lubricant users to expand testing to the many important grease lubricated machines,” says Rich Wurzbach.

Adding to the capability of supporting industry in China is the affiliation of PanAn with Runningland Metrology and Testing (, also founded by David Zhou, which will be offering expert grease analysis in these same markets using the Grease Thief Analyzer technology. “Now in addition to our fuel, lubricants and other condition monitoring tools, we add grease analysis using the Grease Thief technology, to serve our customer base that includes PetroChina, ZF, John Deere, Shell, Lubrizol, Air China, Boeing, Shanghai Metro and more,” says Zhou. “With MRG Labs and the Grease Thief, we can now offer equipment and service solutions in partnership with the recognized technology leaders in in-service grease sampling and analysis solutions worldwide.”
