Heidolph MR3003 Control PT100 Heating plate with Magnetic stirrer

The Heidolph MR3003 Control PT100 is an advanced heating plate with an integrated magnetic stirrer, designed for precise temperature control and homogeneous mixing of liquids in laboratories. Thanks to microprocessor-controlled regulation and support for an external PT1000 temperature sensor (often referred to as PT100), the temperature of both the heating plate and the sample can be controlled with high precision. The device features a digital display, adjustable safety functions, and a robust chemical-resistant housing, making it suitable for routine laboratory testing, chemical analyses, and quality control.
