* Advanced microprocessor controlling system guarantees the reliability and temperature stability
* Bright and clear LED 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 fixed conditions
* Liquid drainage above the control board to prevent liquids from accessing the system
* 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
* When the temperature of the top plate is above 60℃ , hot-top indicator will light up for the user’s safety protection
PLUS serial – Advantages and Applications
* Anti-corrosion top late is easy to clean, can stand high temperatures.
* Ceramic coated stainless steel top plate is suitable for relatively mild heating, good for small sample amounts
relatively low temperature for large volume sample
* WH420 with four positons and WH620 with six positions, each of them can be controlled separetely
* Both of WH420 and WH620 have a timer function for heating.
