Specifications

7 inch square hotplate magnetic stirrers are widely used in chemical synthesis, physical and chemical analysis, bio-pharmaceuticals and other fields.
PID temperature technology precise controls heating process, rapidly reaches target temperature and enhances control accuracy, heating temperature up to 550°C.
7 inch square magnetic stirrers have glass ceramic plate extremely resistant to corrosion and easy to clean. The heating models are suitable for external temperature sensor PT1000, display and control actual medium temperature.

Features
- LED display target and actual temperatures
- External temperature sensor PT1000 is available, display and control actual medium temperature, control accuracy of ±1°C
- Separated safety circuits, fixed safety temperature of 580℃, automatically stops heating once exceed secure temperature
- HOT warning indicates residual hotplate temperature. LCD display would show “Hot” when hotplate temperature over 50°C warning point, even if switched off
