FDR-1701 petroleum products residual carbon analyzer (Ramsbottom method) Overview The instrument complies with the standards ASTM D524 and ISO4262. The standard specifies the amount of residual carbon remaining after evaporation and pyrolysis of the oil and provides some relative coking tendency. It is generally suitable for nonvolatile petroleum products which are partially decomposed at atmospheric pressure. The instrument consists of metal coking furnace, electric control box, sample loader, control ball and glass coking bottle and other components, temperature control part of the use of precision intelligent digital pressure heating, so that the furnace temperature rise evenly, Also used another piece of intelligent digital temperature controller as a coking bottle for temperature calibration use, so the instrument design is reasonable, accurate temperature control. Technical Parameters 1, input power: 220V ± 10% 50HZ 2, the furnace temperature: 550 ± 5 3, heating furnace power: 1500W 4, check the temperature: in line with the standard test method 5.2 requirements 5, coking hole hole: 5 holes 6, sample loader hole: 5 holes 7, the timer: every 20 minutes, 30 minutes once a newspaper 9, ambient temperature: room temperature 25 or so 10, relative humidity:
