The HWCL-1 type heat collecting constant temperature magnetic stirring bath, also known as a magnetic stirrer or oil bath pot, can be used as a water bath or oil bath. The bath is equipped with strong magnetic stirring, and the material temperature is uniform and stable. It adopts PID temperature control method, with high temperature control accuracy. Used as a water bath or oil bath, the bath is equipped with strong magnetic stirring, dual sensors, stable performance, uniform heating, and high temperature control accuracy. Secondary stirring, evenly heated, the stirring mechanism drives the stirring element in the tank to rotate synchronously, which can stir the bath liquid and the sample in the bath simultaneously, evenly heated, and more accurate in temperature. High temperature control accuracy, temperature balance, using PID method to control temperature changes, combined with bipolar magnetic traction design, can achieve higher temperature control accuracy. Adopting a dual sensor design, it can switch between displaying the temperature inside the bath and the temperature inside the reaction bottle, making it easy to use and more efficient.
