GDY-1C High Precision Coal Calorific Value Meter Oxygen Bomb Calorimeter




Calorific Value Tester is designed and made as per GB/T213 “Test Methods for Calorific Value of Coal”, GB/T384 “Test Methods for Calorific Value of Petroleum Products” and Calibration and Inspection Regulation of People’s Republic of China JJG672 “Oxygen Bomb Calorimeter”, as well as the Company Standard of Shanghai Q/YXYY 10 “XRY-1 Oxygen Bomb Calorimeter”.

Oxygen bomb calorimeter for intelligent data sampling process, computer-controlled, automatic test of combustible material calorific value of automation testing instrument, the instrument can be widely used to determine calorific value of combustible substance such as coal, oil, coke and paraffin, etc. It is the best choice of companies in the field of thermoelectricity, smelt, cement, chemical, and scientific research institutes, and institutions of higher learning.


1.Calorific Value Tester adopts a high precision temperature sensor and a high performance A/D converter, and uses a SCM to form the temperature collection and transportation system.
2.The instrument configuration laptop, composed of a high degree of automation, easy to use, convenient and intelligent data compilation instrument.
3.Calorific Value Tester is fully automated in the testing process, after the sample in place, correct input various parameters automatically without manual intervention to complete each test process; you can print measurement data directly on the A4-format printer configuration after the end of the trial.
