1. This instrument adopts all-in-one structure. It consists of two parts: electrical control chamber and high temperature heating furnace. The design is simple and reasonable.
2. It adopts industrial computer control system machine system. The instrument controls the whole procedures automatically according to program preset.
3. The screen adopts all English interface. Operator can do determination by prompts on the screen even no need to read the operation manual. Easy to operate.
4. It controls the flow rate of nitrogen, temperature heating rate and preset temperature automatically. Easy to adjust the flow rate. The heating rate is accurate and temperature control is stable.
5. Automatically collect test data, automatically calculate test results, and export files through USB serial port.
6. The measurement range of this instrument is 0.10%(m/m)~30.0%(m/m). The test result is equivalent to Conradson method if the carbon residue is higher than 0.10%(m/m).
7. This instrument is also suitable for petroleum products with a residual carbon value below 0.10% (m/m) and composed of distillate oil. However, the 10% (V/V) distillation residue should be prepared using the GB/T 6536 method first, and then determined using this instrument.
8. There is no statistically significant difference between the measurement results obtained by this instrument and those obtained by Conrad residual carbon method in the range of 0.10% - 25.0% (mass fraction).
