Digital Hot Plate / Stirrer
Model: WH620
PRODUCT DESCRIPTION
- 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 temperature setting, 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.
Standard PT100 temperature sensor
Accurate solution temperature within ±1℃ in general range.
LED selectable
Accurate solution temperature within ±1℃ in general range.
Standard PT100 temperature sensor
Display temperature and speed at the same time, and remember the last working parameters.
Ceramic top plate
Great anti-corrosive ability to acid, base, or organic solvents.
Safety protection
Flashing high temperature indicator, warning for hurt by touch.
Liquid drainage
Above the control board Avoid the solution splashing on the touch board.
