Description: 
 DYYB Brand DL series uses low-temperature cooling liquid circulating pump fully enclosed air-cooled refrigeration compressor and microcomputer intelligent control system to provide low-temperature cooling water (liquid) flow or low temperature water (liquid) flow, in order to satisfy the cooling water and low-temperature liquid to cooling or constant temperature equipment, such as rotary evaporators, fermentation tanks, electron microscopy, low temperature chemical reactor, electron spectrometer, mass spectrometer, densitometer, freeze-drying apparatus, vacuum coating apparatus, the reactor and so on. Volume can also be put directly in the tank a variety of low temperature experiments. 
 Features: 
 ★ closed air-cooled refrigeration compressor, the microcomputer intelligent control system to automatically turn on cooling, refrigeration systems with time delay, overheating, over-current protection devices, such as multiple 
 ★ circulating pump liquid output can be cold tank, cooling, or temperature machine outside the experimental temperature field in a second container or 
 ★ has a sleep timer function computer, turn this function from 0 to 100 hours of time off any time set 
 ★ uses the double window, red, green, two colors LED display temperature settings and temperature measurements, digital resolution of 0.1 ℃, computer can correct the deviation of temperature measurement, the number was 0.1 ℃ accuracy 
 ★ All the above operations are intelligent controller in the computer soft touch on the press to complete, easy to operate
