Automatic Residual Carbon Analyzer Astm D4530 Micro Method 0.10%M/M-30.0%M/M

SH109 Automatic residual carbon analyzer

The SH109 fully automatic residual carbon analyzer is designed and manufactured in accordance with the requirements of GB/T 17144-2021 "Determination of residual carbon in petroleum products (micro method)", "ASTM D4530" and "ISO 10370:1993" standards. It has the characteristics of beautiful appearance and easy operation. The test results are consistent with those of GB/T268 (Conics method) and are also suitable for detecting petroleum products composed of distillate oil with residual carbon values below 0.10 (m/m).

Petroleum residual carbon: The residue formed by the gas decomposition products emitted from an oil sample after heating, evaporation, and cracking. Expressed in terms of quality score

Principle: Place the weighed sample into a sample tube and heat it up to 500 ℃ in an inert gas (nitrogen) atmosphere according to the prescribed temperature program. The volatile substances generated during the reaction process are carried away by nitrogen, and the carbonaceous residue left behind is reported as a percentage of the original sample to determine the trace residual carbon value.

Main technical parameters and performance characteristics:

● Adopting a 5-color LCD touch screen with automatic calculation and optional printing function, the motherboard is equipped with a communication interface.

● Adopting full temperature rise process program control, the heating rate is automatically controlled, the set temperature is automatically controlled, and the temperature control is stable.

● The display instrument is in one of the states of "blowing", "heating up", or "constant temperature"

● Adopting an embedded operating system, automatic control of temperature rise and flow rate, and real-time display of experimental progress
