Key Features

• ✓Measures nitrogen or protein content, detects ammonium salt, volatile fatty acids/alkali, soil cation exchange capacity, and more.
• ✓Dual Mode Operation: Manual and automatic modes. In automatic mode, the analyzer:
• ✓Quantitatively adds lye, boric acid, and dilution water.
• ✓Includes automatic waste discharge and rinse setting.
• ✓Customizable Distillation: Adjustable distillation time with alarm notifications for process completion. Includes safety door protection and alerts for improperly placed digestive tubes.
• ✓Water Conservation: Condensed water flow rate of 1.5 L/min with real-time flow monitoring and low water pressure alarm.
• ✓Real-Time Monitoring: Tracks steam generator temperature, pressure, and water level to ensure a safe experiment.
• ✓Emergency and Fault Detection: Emergency stop function, automatic fault detection, sound and light alarms, and intelligent display.
• ✓High-reliability PTFE pump with corrosion resistance, anti-crystallization, stable liquid addition, and negative pressure suction. The analyzer is made from ABS engineering plastics, offering corrosion resistance, waterproofing, and leak-proofing.

Applications

Wide Usage: Ideal for fields including food processing, feed production, tobacco, animal husbandry, soil fertilizer, environmental monitoring, medicine, agriculture, scientific research, teaching, and quality supervision.
