GDY-1A+ Oxygen Bomb Calorimeter




The instrument 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 GDY-1 Oxygen Bomb Calorimeter”.

 It has been widely used to determine heat value of coal, oils, tar, and paraffin, etc. It is the desired instrument for power plants,

smelting, cement, and petrochemical, scientific research institutes, and colleges and universities.

Main characteristics:

1. The instrument adopts a high precision temperature sensor and a high performance A/D converter, so it us precise.

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

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