Microprocessor-Based: MS300/400 hot plate magnetic stirrer is designed in high performance digital circuit and CPU, The maximum temperature can be up to the range of 300 to 400oC. Digital Speed Control: The stirrer is press-key designed to adjust speed, which prevent the stirring bar from stopping. The indicator display the stirrer's motor speed. Setup: MS300/400 can set object temperature, hold temperature, stirring time and other parameter that make your work easy. Automatic Temperature Control: Connecting the temperature sensor into the stirrer, so that it can measure temperature and control object temperature, the accuracy is 1oC.
