7" Digital Magnetic Stirrer AMT550   
- External temperature sensor PT1000 is available, real-time control medium temperature.
- Simple & easy operation. Automatically identify temperature sensor PT1000 and transfer to PT1000 operation mode. Record and display the last running parameters when switch on.
- LCD display target and actual temperature, as well as set speed and actual speed can be displayed.
- PID temperature technology precise controls heating process, rapidly reaches target temperature and enhances control accuracy Brushless DC motor maintenance free and explosion-proofed, accurately control speed
- Separate safety circuits with 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.
- Free software, computer can control and document all operation values via RS232 interface
