Laboratory LCD Digital 5-Inch Timed Heating Type Strong Magnetic Stirrer for Viscous Sample
DMS5-340 LCD Digital-Control 5-Inch Timed Heating Magnetic Stirrer
Features：
*Ceramic coated aluminium disc surface for corrosion resistance and easy cleaning.
*The corrosion-resistant all-metal housing provides good heat dissipation and reliable fire protection.
*Selected high-temperature resistant strong magnetic magnet, strong stirring, suitable for viscous liquid stirring.
*DMS5-340 powerful parallel magnetic field, any position of the disc, the magnetic field strength is uniform, suitable for parallel reaction; DMS5-340M strong magnetic field, suitable for viscous samples.
*High protection classlP41.
*Heating modes are divided into: A rapid heating mode, B standard heating mode, C stable heating mode, to meet different customer needs.
*Safety lock to prevent accidental change of operation.
*Buzzer: When the machine malfunctions, or the timer function counts down to the end of the buzzer will emit a “drip drip drip” sound.
*Heat warning function: when the disc temperature is higher than 50 °C, turn off the heating, the screen will have “HOT” flashing tips, even if you turn off the power, 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 power supply to protect the operator’s safety.
*DC brushless motor, no spark, long life; low noise, maintenance-free, smooth running.
*LCD displays RPM, time and temperature parameters 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 heat damage to the sample.
*Remote control function with PC connection.
*A wide range of accessories and complete, suitable for colleges and universities, scientific research, enterprises and other professional chemical synthesis laboratory.
*Safety temperature can be set.
