Product Introduction：
SG-3047 High temperature super-powerful electric mixer is the company to meet the precise temperature control in the sample under the conditions of mixing experiment needs special mixers developed a new product，The thermostat function can operate in a mixed sample, while the samples to achieve precise heating and temperature control （temperature control range: room temperature -200 ）.use high-quality electrical and heating components selected by advanced processing of this series of mixers, to provide users with an ideal mixing precise temperature control equipment, filled the blank of similar products。stirring rods of stainless steel or Teflon material （customer self-selection）, has superior corrosion resistance.
SG-3047 High temperature super-powerful electric mixer is to meet the requirements on the speed with precise control, and mixing the sample volume, high viscosity, while temperature control of samples required mixing, stirring speed mixing and other special purpose ultra-low specific developed a new electric blender products, similar products to fill gaps, provide customers with an ideal experimental tool for the right。Speed with low speed precision mixing and the ability to control speed digital, direct and reliable speed control accuracy of 0.1 rev / min speed range from 0 r / min to 2600 r / min （Note: There are 2 types of motors） Please select users according to their needs: a large forces for the low-speed motor, reflecting the low-speed large-capacity high-precision mixed ability，Low speed, high-strength，The maximum speed can reach 1400 r / min，Another contrast, less power at low speeds，the greater the speed the greater the force，The maximum speed can reach 2600 r / min、adjustable speed。Large capacity suitable for high viscosity samples, the maximum capacity of up to 80L stirring. The instrument has automatic protection, explosion-proof capability, long life, safe and reliable.
Heating round bottom parts are the difference between the end of peace, please Choose one of our customers as needed, to provide collectors round bottom heating mode, reduce losses, can greatly improve the precision of temperature.

Features：
SG-3047 , with the novelty appearance, easy to use effective, durable, safe, reliable, long-term uninterrupted operation speed digital display, digital temperature control, high precision, control accurate and reliable, etc.Speed steady, continuously adjustable, small voice, stirring rod made of stainless steel or Teflon material （customer self-selection）, corrosion resistance, additional control box can operate away from the table. Good performance, to meet your various needs of different work environment.
