Introduction: The instrument is designed and manufactured in accordance with GB / T 17144 "Residual Determination of Petroleum Products", "ASTM D4530" and "ISO 10370: 1993". With beautiful appearance, easy to operate features. The test results are consistent with the GB / T268 test results. Features: (1) only a small number of samples can be tested: Residual carbon content (%) <1> 1-5> 5 Amount of sample (g) 5.0 ± 0.5 0.5 ± 0.1 0.15 ± 0.05 (2) Twelve samples can be measured simultaneously. (3) the use of nitrogen to protect the air, to ensure that the test conditions can be achieved without good reproducibility and reproducibility. (4) the use of trachea export method exhaust test exhaust gas, compared with the Kando method for the experimental site requirements more freedom and flexibility. (5) The use of axial fans to cool, help to reduce the temperature of the instrument. (6) operation only need to press the "start" button, all by the instrument automatically test, normal without any operation and judgment, after the end of the trial, the buzzer prompts the end of the trial. Technical Parameters: Measurement range: 0.10% (m / m) -30.0% (m / m) Dimensions: 230mm × 320mm × 425mm Combustion chamber size: Φ85mm × 105mm (diameter × height) Combustion chamber operating temperature range: room temperature - 500 ℃ Combustion chamber temperature accuracy: 500 ℃± 2.0 ℃ constant temperature 15min Set time error: <0.1s Pressure adjustment range: 0 kPa (0 kg / cm2) - 392 kPa (4 kg / cm2) Flow adjustment range: 100ml / min-1000ml / min; 150ml / min and 600ml / min automatic switching; Waste collection bottle specifications: 200ml, threaded interface glass bottles; Exhaust pipe diameter: Φ12mm Heater power: 1000W Air consumption: pressure of 14700kPa (150kg / cm2) of the standard nitrogen bottle, 100 times / bottle Maximum number of samples: 12 or 6 samples Equipped with a sample tube: 2mL or 4mL quartz sample tube (for old oil), 15mL or 16mL quartz sample tube (for new oil), and matching sample holder: both old oil tube with 12 holes, There are new oil with a tube rack 6 holes, but also with a new old oil can be used in the tube rack 9 holes
