Compare

*  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 for high temperature
*  Ceramic coated stainless steel top plate is suitable for relatively mild heating, good for small amount sample or a 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 the timer function

WH420 / WH620 Heating and stirring in parallel

* The multiple talents of WH420/WH620 are particularly suited for laboratories in which highly differing tasks are to be
coped with.
