550℃ 10~20L Laboratory LCD Digital Control 7Inch Heating Powerful Magnetic Stirrer with Timer for Viscous Liquid Stirring

Features
* Ceramic discs are extremely corrosion-resistant, resistant to strong acids and alkalis, and high temperatures, making it easyto clean accidental drips of solvents, oils, or other contaminants.
* The corrosion-resistant all-metal housing provides good heat dissipation and reliable fire protection.
* High-efficiency infusion platform and waterproof edge design prevents liquid from entering the interior of the machine andcorroding electronic components.
* Selected high-temperature resistant strong magnetic magnet, strong stirring, suitable for viscous liquid stirring.
* Heating modes are divided into: A rapid heating mode, B standard heating mode, C stable heating mode, to meet different customerneeds.
* Safety locks to prevent accidental changes inoperating conditions.
* Buzzer: When the machine malfunctions, or the timerfunction counts down to the end of the buzzer will emit a "drip drip drip"sound.
* Residual heat warning function, when the disc temperature is higher than 50 ℃, turn off the heating the screen will have a "HOT"
flashing prompt, even if the power off, the display is still "HOT" flashing to remind the high temperature.
* Two independent safety circuits are designed to continuously monitor the equipment. When overheating occurs, the sensor fails,the machine reports an error and stops heating, and when the line is short-circuited, the machine automatically cuts off the powersupply to protect the operator's safety.
* DC brushless motor, no spark, long life; low noise, maintenance-free, smooth running.
* The LCD displays the set and real-time values of speed, time and temperature in an intuitive and clear manner.
* Timing function, timing range 1min-99h59min, countdown to the end of the stop heating, will not stop stirring, so as not to heatdamage to the sample.
* Remote control function with PC connection.
* Safety temperature can be set.
