* Advanced microprocessor controlling system guarantees the reliability and temperature stability
* Bright and clear LCD digital display and setting for the working temperature, stirring speed, working time, and safety temperature
* Memory function for stirring speed and setting temperature, convenient for experiments with _xed conditions
* Liquid drainage above the control board to prevent liquids from accessing the touching board and the electronics
* Direct connection for Pt100 temperature sensor for convenient solution temperature control
* Sealed outer shell and isolated critical parts design for enhanced longevity even in a harsh laboratory environment
* New enhanced infrared heating element, is a type of high temperature hot plate stirrer with very high heating density, can reach a high media temperature
* High safety protection: When exceeding the safety range of the hot top (50℃ more than the setting temperature) or solution (adjustable for WH240-R), the heating can be shut off immediately and automatically for the safety protection
