Description
The MS?H?Pro+ LCD Digital Magnetic Hotplate Stirrer combines reliable magnetic stirring with accurate heating in a robust laboratory instrument. It features a brushless DC motor that is maintenance?free and spark?free, ensuring long service life and dependable performance. The digital temperature control reaches up to 340??C and the speed control goes up to 1500?rpm, with an LCD display showing actual temperature and stirring speed for precise adjustment. A large stirring capacity of up to 20?L of water allows handling of substantial sample volumes. Built?in safety circuits provide overheating protection, and a ?HOT? warning flashes when the surface temperature exceeds 50??C, even after shutdown. External temperature control using a PT1000 sensor enhances measurement accuracy, while the ceramic?coated stainless steel work plate offers excellent chemical resistance. Remote PC control and data transmission are also available, making this stirrer adaptable to modern laboratory workflows.
