WDL-9A Microcomputer Sulfur Determination Apparatus

The microcomputer-controlled sulfur determination apparatus is based on the principle of coulometric titration (refer to GB/T 214—1996). The single-chip microcomputer system is responsible for controlling the temperature rise of the high-temperature furnace, collecting data on temperature and measurement results, and transmitting the data to the main control computer. The computer system processes the data, displaying furnace temperature, measurement results, sample feeding position, and other information, while sending control commands to the single-chip microcomputer system. When the device operates in offline mode, the single-chip microcomputer system independently completes all tasks. The instrument can work with a computer or operate offline. To enter computer-controlled mode, press the OK key or any non-numeric key while turning on the main power. To enter offline mode, press any numeric key while turning on the main power. If no selection is made, the system will revert to the previous state.
