Brief introduction: Hangzhou heung rain instrument dlsb-5/30 low-temperature coolant circulation pump rotating steam cooling equipment manufacturer direct-selling air-cooled fully enclosed compressor unit refrigeration, microcomputer intelligent control refrigeration system automatic opening, refrigeration system with delay, overheating, over current and other multiple protection devices. Features: 1. Air cooled fully closed compressor unit refrigeration. The microcomputer intelligent control refrigeration system is automatically turned on. 2. The circulating pump can output the cooling liquid in the tank, cool the experimental vessel outside the thermostat or set up the second thermostat field. 3. The microcomputer is equipped with the function of timed shutdown, which can be set at any time within 0 to 100 hours. 4, with double window, red, green two color LED display temperature value and temperature measurement, display resolution 0.1 ℃, the microcomputer can be fixed temperature measurement deviation, the digital display precision of 0.1 ℃. 5. With the function of microcomputer software lock, the set value of each parameter of the system can be locked. Irrelevant personnel cannot change the set parameters. 6. All the above operations are completed by pressing and touching the soft key on the computer intelligent control instrument. The operation is simple. 7. The product is easy to use and can work continuously.
