Introduction:

GDY-1A+ Oxygen Bomb Calorimeter is designed and made as per the national standard of People’s Republic of China GB/T213-2008 Test Method for Calorific Value of coal, GB/T384-1988 Test Method for Calorific Value of Petroleum Products and Calibration Regulation of People’s Republic of China JJG672-2001 Oxygen Bomb Calorimeter, as well as Shanghai enternprise standard Q/YXYY 10 GDY Series Oxygen Bomb Calorimeter.

Main Technical Features:

GDY-1A+ Oxygen Bomb Calorimeter adopts technology of single chip microcomputer, LCD screen, high accuracy temperature sensor and high performance A/D conversion device. It is a highly intelligent instrument.
The test procedure is fully automatic. After placing sample and inputting right parameters, the instrument will finish all the procedures without manual interference. It will print the test data directly after test is over.
GDY-1A+ Oxygen Bomb Calorimeter adopts sealed oxygen bomb. The whole structure adopts stainless steel material.The strength is enough to resist 20MPa hydrostatic test under room temperature.
