The digital display constant temperature oil bath is mainly used as a supporting instrument for some experimental equipment such as rotary evaporator, and can also be used as a thermostat alone. The oil tank is made of imported high-quality stainless steel plate and precision machining technology, and has the characteristics of high temperature resistance and corrosion resistance. The temperature control device adopts high stability operational amplifier and double integral high-precision A/D conversion technology: far infrared heating technology is designed, coupled with magnetic stirring, the product heat balance time is short, temperature fluctuation is small, uniformity is good, and LED display is accurate , Intuitive. This product is widely used in distillation, drying, concentration and warming chemicals or biological products.
