The incubator shaker uses three-axis eccentric balance movement, which is stable and reliable and has long service life. The speed control system has a speed terminal feedback system to keep the machine oscillating with high precision. The combination and innovation of PID control technology and fuzzy control technology realize the high precision control within the temperature range. Application of variable frequency compressor refrigeration, high efficiency, small temperature fluctuation, stable control. It can be equipped with advanced WiFi monitoring system, which can remotely monitor the same machine by multiple mobile phones at the same time, and timely obtain the alarm information such as no air intake, so as to quickly deal with the emergency situation and protect the cultured cells. Suitable for medium to large scale experiments.
