A:Product  Introduction:

 DSHD-268 Carbon Residue Tester is designed according the national standard of People's Republic of China GB/T268 Test Method for Carbon Residue of Petroleum Products by Conradson Method.

 DSHD-268 Carbon Residue Tester is used to determine the amount of carbon residue of petroleum products after evaporation and pyrolysis,  thus to check coke forming property of petroleum products.

B: Main technical specifications and parameters:
1. Burner: a gas burner of Meker type

2. Porcelain crucible: low type,  about 30 ml

3. Inner iron crucible: made of iron sheet,  75±5 ml,  its surface is black

4. Outer iron crucible: made of iron sheet,  190±10 ml; it is with a cover and its surface is black

5. Tripod: made of iron. Its surface is plated with nickel and chromium, and it is polished. It is 250±10 mm high and its ring diameter isdiameter 130±5 mm

6. Round iron shield: it is made of iron plate,  the thickness of which is 8 mm. the height of lower parts is 50mm-53 mm. The height of cone in the middle is 25±2 mm. There is a piece of diameter 3 iron wire welded on the upper section of round tube. The iron wire is bent to a fire bridge of 50±3 mm in height,  which is like a mouth. The fire bridge is black and is used as an indicator for the maximum height of the flame.
7. Flame shield: it is made by pressing a piece of 0.6-0.8 mm thickness iron plate. The diameter of upper opening of the middle hole is diameter 90±2 mm,  and the diameter of lower opening is diameter 82±2 mm. It contains an asbestos pressure ring. The other type of flame shield contains three bending feet in the hole of flame shield to support the crucible.
