Digital Overhead Stirrer

Product description: Digital overhead stirrer is suitable for middle and high viscosity liquid or solid-liquid mixture. It mainly used in chemical synthesis, pharmaceutical, physical and chemical analysis, petrochemical, cosmetics, health products, food, biotechnology and so on.
Product Features
1, LED with backlit display speed and torque real-time.It’s convenient and accurate for readings, easy to operate.
2,Precise control speed. Control accuracy is ± 3rpm. Accurately display the speed actual value / set value.
3, Constant speed.Torque can be adjusted automatically according to the sample viscosity change to keep the set speed.
4, Full explosion-proof equipment. Explosion-proof brushless DC motor to ensure lab safety.
5, Anti-spill samples, smooth start, effectively prevent spilling.
6, Closed shell to prevent liquid from entering the machine internal corrosion circuit, ensure safe operation. Long time continuous and stable operation.
7, Overload protection and motor protection. When overload,short circuit and abnormal speed occur,it will cut off the circuit and alarm automatically  to ensure running safety and lab safety.
8, Open RS232 data output connector.Computer via RS232 interface enables remote control and save the data.
