The WIGGENS new hotplate stirrer enjoys the benefits of Schott glass ceramic surface such as chemical resistance, a high surface quality, and a resistance to temperature shocks of more than700℃ , providing the users with optimal solution compared to conventional heating surface materials. The high infrared permeability ensures that the heating energy is transferred quickly and with very limited loss. i.e. it heats liquids fast and thus saves time and energy. PID control enables good temperature stability. If the Pt-100 sensor is connected, temperature-controlled work with stability of ± 1℃ can be reached in most applications.
All functions can be viewed and monitored on a large and clear LCD display, including most frequently used parameters like working temperature, stirring speed, working time, and safety temperature etc.
> 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 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.
> High safety protection: When exceeding the safety range of the hotplate (10-50 ℃ adjustable) , the heating can be shut off immediately and automatically for the safety protection.
> ICC technology to self-optimize for optimal heating results.

TFT high-definition color touch screen
Synchronous display of set temperature, actual temperature, and rotational speed. Automatic memory of the last set working parameters.

Two external sensors can be connected
The first PT100 is used to test and control the sample temperature, and the second thermocouple is only for reference temperature value.

Ceramic glass 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.

Intelligent Cascade Control
self-optimizing, for optimal results. Excellent temperature stability.

Overheating protection
If the internal temperature exceeds the permissible temperature that may damage the internal electronic components, the heating power will be reduced automatically.

RS232 interface
Enable the unit to be connected to a PC for operating.

Safety Temperature
is an adjustable temperature safety circuit that prevents from exceeding a specified set temperature. The safety temperature can be adjusted by using a special tool included in the product delivery.

Sensor in medium detection
If the sensor falls during the heating process, it will automatically trigger the device alarm.

Direction of rotation
Clockwise or counterclockwise.
