Successfully developed the Infrared Carbon and Hydrogen
　 Analyzer which is the only one that can automatically changing
　 crucibles and it remarkably promoted the level of automation of
　 carbon and hydrogen analysis.

　 The originated SDLA series Proximate Analyzer which can test continuously
　 with a lot of batches, which greatly improved the efficiency
　 of Proximate Analyzer. It is the only Proximate Analyzer that
　 can finish testing 3 to 6 batches of coal samples with all indexes
　 in 8 hours at home an abroad.

　 Developed SDC311, original technology of using spiral
　 pipe to make all points isothermal. It's the only one that
　 can run well in severe environment and the test results
　 are accurate with the test time less than 11min at home
　 and abroad.

　 Developed SDS616 Coulometry Sulphur Analyzer which
　 first adopts flow stability and balancing technology and
　 automatic sample transfer instrument in China . The test
　 process realized unattended operation.

　 Developed SDTGA5000 Proximate Analyzer which made
　 a great progress on precision and accuracy of the test data.

　 Developed the first SDACM5000 Calorimeter in China
　 which has three layer constructions and doesn't affect
　 by ambient temperature variation.

　 Developed the first automatic Proximate Analyzer
　 SDTGA2000 in China , which greatly improved
　 automation of proximate analysis

　 Developed the first automatic Calorimeter in China ,
　 which promoted Chinese Calorimeter industry into
　 a real automatic period.

　 Developed SDC-IIIa Calorimeter, which firstly
　 carried out asynchronous multi-control technology.
