Product Introduction：
SG-3039 Series Digital thermostat  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, stirring rods adjustable angle （0 degrees -30 degrees）。Digital temperature control, digital speed, high precision and reliable control。
New research projects to meet the needs of modern laboratories, SG-3039 Series Digital thermostat  electric mixer adopted by the use of advanced power steady speed line, no load can be more than 10,000 hours continuous operation, with speed and stability, torque, noise, etc, and loved by the majority of users。With mechanical timer, simple, smooth operation, variable speed, small and powerful motor speed in a wide range of high viscosity of the liquid solution for precision and stability of the mixing, especially for large volume samples, is petroleum, chemical industry, medicine and health, environmental, biochemical laboratory, analysis room, an indispensable tool for education and scientific research。reliable, low-speed work remains to ensure a strong rotation speed and stability of oil, chemical resin adhesive, oil and other viscous solution can be mixed with good performance properties, get the majority of users.

Features：
SG-3039 Series Digital thermostat  electric mixer with novel and beautiful shape, easy to use effective, durable, safe, reliable, long-term uninterrupted operation, digital temperature control is accurate and reliable precision. The machine used DC motor, with increased functionality, speed stability, variable speed, rotational speed digital, voice small, stirring rod made of stainless steel or Teflon material （customer self-selection）, corrosion resistance, reprovision control box can operate away from the table. Performance, to meet your various needs of different work environment。
