Products Introduction：
LYH series of precise digital control of low-temperature cooling cycle trough is own heating and cooling source of high-precision thermostatic。It is widely used in petroleum, chemical, metallurgy, medicine, biochemistry, physical testing and chemical analysis research departments, universities, factories and measurement of laboratory quality control department。In the bath for constant temperature experiments, can also be connected by hoses and other equipment, as supporting the use of constant source，Such as rotary evaporators, gel electrophoresis apparatus, viscometer, medical cold cap, cooling blankets, etc., or to other devices used for cooling，Such as electron microscopy, molecular pumps, ion pumps, diffusion pumps, microwave therapy machine。Work for the user to provide a hot and cold controlled temperature constant even field source, the test sample or production of products constant temperature test or tests, but also as direct heating or cooling and heating or cooling auxiliary heat source or cold source.

Features：
1 Air-cooled compley closed refrigeration compressor, microprocessor based control system to automatically open the refrigeration，refrigeration system with time delay, overheated, over-current protection devices。
2. Circulation pump can be slot （machine） within the cold liquid output, cooling or temperature outside the aircraft container or a second temperature experiment field。
3Microcomputer equipped with timer turn off function, this feature can be turned from 0 to 100 hours to set the time off any time。
4. Temperature and time digital display; LED Display temperature settings and temperature measurements, temperature measurements may be amended computer error, so that the temperature accuracy up to ± 0.05 ℃。
5. Temperature difference back to 0.2 ℃ ~ 19.9 ℃ in the range of any set, make the cooling water （liquid） temperature fluctuation and the energy consumption of the machine to achieve the best energy-saving option.
6. With computer software lock can lock the system parameter settings, regardless of the staff can not change the configuration parameters。
7. All of the above operations are inligent controller in the computer press the touch pad on the completion of simple。
8. Product easy to use, can work. Dynamic temperature control system, quick response and a small degree of temperature fluctuations。
9. Liner, tops are all high quality stainless steel, clean, beautiful and corrosion resistance；
10. Small size, light weight, low noise
