1. Secure your lab with SmartPresence™ and SmartLink™ technologies. These dedicated functions will automatically shut down the heater if no one is detected after a user-defined "timeout" period.
2. This is an industry leading early detection system that uses two independent safety control systems to continuously monitor the electronics and will shut down the heating before an overtemperature condition occurs.
3. Accurate stirring from 60 to 1600 rpm is made possible by designing powerful motor, strong magnet and software-controlled ramp speed, ensuring safe magnetic coupling for viscous applications.
4. USB port provides flexibility for repetitive application programming and enhanced security with SmartLink™ technology.
5. The smarthouse™ is cool to the touch and resistant to chemicals.
6. Heater disconnect switch.
7. Built-in support rod seat.
8. IP21 ingress protection.
9. Ceramic or aluminum surfaces are easy to clean.
10. Hot top indicator.
