Product overview & key features

Product Features：

The ceramic-coated plate offers excellent corrosion resistance, capable of withstanding strong acids, strong alkalis, and high temperatures. It is easy to clean spilled solvents, oils, or other contaminants.

The corrosion-resistant full metal housing provides good heat dissipation and reliable fire protection.

The efficient drainage platform and raised waterproof edge prevent liquids from entering the machine and corroding internal electronic components.

Selected high-temperature resistant strong magnets provide powerful stirring force, suitable for mixing viscous liquids.

The safety lock prevents accidental changes to the operating status.

Buzzer: When a fault occurs or the timer countdown ends, the buzzer emits a "beep beep beep" alert sound.

Residual heat warning function: When the plate temperature exceeds 50°C, heating is turned off and the screen displays a flashing “HOT” warning. Even after power-off, the display continues to flash “HOT” to indicate high temperature.

Dual independent safety circuits continuously monitor the device. In the event of overheating or sensor failure, the machine shows an error and stops heating. If a short circuit occurs, the power is automatically cut off to ensure operator safety.

The brushless DC motor is spark-free, long-lasting, low-noise, maintenance-free, and runs smoothly.

The LCD displays both set and real-time values for speed, time, and temperature, providing clear and intuitive readouts.

Timer function: Settable from 1 minute to 99 hours 59 minutes. When the countdown ends, heating stops but stirring continues, preventing thermal damage to samples.

Remote control function is available, allowing connection to a computer.

Safety temperature can be preset.
