Product Introduction：
SG-4057 CNC Super constant temperature oil bath made of imported quality stainless steel and precision machining process, it has a high precision temperature control, corrosion resistance, compact structure, beautiful appearance, saving energy, long life。Imported high-quality oil pump as the power cycle solved the oil temperature unevenness of the weaknesses, the precision of temperature control equipment and oil temperature uniformity required to achieve a higher。temperature control device operational amplifier with high stability and high precision double integral A / D conversion technology: far infrared heating technology design, the product a short time heat balance, temperature fluctuation, even good, LED display accurate and intuitive. The product is widely used in distillation, drying, concentration and temperature and chemical or biological products, stains。can also be used for constant temperature heating and other tests, biological, genetic, virus, fisheries, environmental protection, medicine, health, biochemistry laboratory, analysis room, an indispensable tool for education and scientific research。

Attention
1、To ensure safety, please connect ground when you use.
2、Do not use no oil inside the container.
3、When not in use, switch off the power supply to avoid accidents.
4、Use must be refueled in the pot, plug in the power, digital temperature table shows the actual measured temperature, knob switch, while observing the readings to the desired temperature setting, When the oil temperature exceeds the set temperature, the heat indicator light, that heater has begun to work, When the oil temperature to reach your desired temperature, the temperature indicator light, heat light goes out. Should be noted that the oil pan heating pipe can not be exposed oil surface, it would burn heating pipes, causing leakage phenomenon.
