A:Product  Introduction:
DSHD-508 Ash Content Tester is designed according the national standard of People's Republic of China GB/T17144 Test Method for Carbon Residue of Petroleum Products by Micro-method. Its function is to determine the carbon residue of petroleum products.

 DSHD-508 Ash Content Tester also could be suitable to determine the petroleum products composed of distillate oil which carbon residue is lower than 0.10%(m/m).But it should prepare 10%(V/V)distillation residue by method of GB/T6536 firstly and then doing determination with the instrument.
 The range of carbon residue determined with the instrument:0.10%(m/m)-30.0%(m/m). To the products which carbon residue exceed 0.10%(m/m), the test result is equivalent with the carbon residue tester(Conradson Method).
