Functions and Features
•The golden ratio design combined with a sleek blue shell presents a streamlined, technological aesthetic. The ergonomic design ensures comfortable and effective operation.
•The 5-inch LCD screen offers a wide viewing angle, providing clear visibility from any perspective.
•Setting parameters is simple, and displacement adjustments are more efficient.
•With Lead Fluid’s patented calibration algorithm, it conserves three times the original liquid and boosts efficiency by threefold.
•The three-level permission management system is particularly suitable for pharmaceutical factories and other industrial environments.
•No rewiring needed, easily switch between different analog types.
•Offers multiple communication modes, including network communication.
•With 400w power, it can cascade up to 10 pump heads
•Designed for wide voltage ranges, suitable for 110-240V.
