Summary of Use:It is widely used in the field such as petroteum,chemicalindustry,metallurgy, medicine, biochemical engineering, physi cal performance testing and chemical analyzing in the researching department,altitude academy,factory laboratory and metering quality inspection.The constant temperature test can be carried out in the thermostatic bath.. It also can be connected with other equipment through the tube,which can be formed a complete set and then usd as constant temperature source such as rot atory evaporator electrophoresis appearance, viscometer,medical cold hat,decreasing temperature blanket and so on,or can be applied for other equip ment such as electron microscope, molecular pump,ion pump,diffusion pump,microwave remedial machine and so on.Characteristics:1.Low liquid level monitoring protecting is provided,when the liquid level in the tank is gradually depressed because of medium volatilization or outercirculating pump pipe cracked for aging or some other reasons,the low liquid protector equipment will cut off the electric heating up system,and set out thealarm sound in the mean time, in this way it can make sure the safety of apparatus and samples.2.Temperature measured value and temperature setting value can be displayed separately on the LED double window.3. Controlling system has the functio9n of ultra-high temperature protection,sensor abnormity protection;while the refrigeration system has the function of excessive heating and over-current automatism protection.4.According to the big space refrigerating theory,the completely improved evaporator is adopted, temperature can be decreased more rapidly and the temperature is moreequal.5.Professional electrocircuit with PID output which is totally newly designed, and the temperature controlling is more exactly.6.Inner wall and table-board are all made of stainless steel,clean and sanitation,beautiful and corrosion resistance.7.Use of environmentally friendly cfr-freerefrigeration cooling airflow.
