GDY-1B  Coal Oxygen Calorimeter / oil calorimeter/ paraffin oxygen calorimeter

The Coal Oxygen Calorimeter  is designed and made as per the National Standard GB/T213 "Test Methods for Heat of Coal", GB/T384 "Test Methods for Calorific Value of Petroleum Products", the National Measurement and Determination Specification JJG672 "Oxygen Bomb Calorimeter", as well as the Shanghai Company Standard "Q/YXYY-10 XRY-1 Oxygen Bomb Calorimeter". The Coal Oxygen Calorimeter has been widely used to determine heat value of coal, oils, tar, and paraffin, etc. The Coal Oxygen Calorimeter is the desired instrument for power plants, smelting, cement, and petrochemical, scientific research institutes, and colleges and universities.

Main characteristics:

1.The Coal Oxygen Calorimeteradopts a high precision temperature sensor and a high performance A/D converter, so it us precise.

2. The Coal Oxygen Calorimeter  uses a microprocessor to form the intelligent temperature controlling system, so it can accurately control temperature in high accuracy.

3. The Coal Oxygen Calorimeter can print out test data automatically. It is automatic and it is easy to be operated.
