摘要: An automatic mixing system for detecting soil nutrients by absorption spectroscopy includes an injection pump, a liquid storage ring, multi-channel switching valve, cleaning peristaltic unit, process control chamber three-way solenoid uniform spiral photoelectric detection unit and gas-liquid separator. The pump is connected with the valve through separator tee, withthe ring tee. invention aims to provide feeding, of solution preparation, improve nutrient precision efficiency reduce errors caused operations in detection.
