Oxygen Bomb Calorimeter

BD-OBC-1A+ Oxygen Bomb Calorimeter

Product Introduction

BD-OBC-1A+ Oxygen Bomb 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”.

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 technical features

The instrument uses a single-chip control technology, color LCD display, high-precision temperature sensor and high-performance A / D conversion device, consisting of a high degree of automation, screen effect is good, easy to use, convenient intelligent data compilation instrument.
The instrument 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.
This instrument adopts the self sealing type oxygen bomb, all the structure is made of stainless steel, and the strength is enough to withstand the pressure test of 20MPa at room temperature.
The inner tube of the instrument is made by stainless steel sheet, section of pears, put the barrel of water was 3000 grams, water cylinder with electric blender, to ensure that the inner tube water bath temperature uniformity.
The instrument of the external water jacket is a double container and experiment when filled with water, through the water jacket mixer to cylinder in uniform temperature, formed to meet the test requirements of the constant temperature environment.
