Low temperature constant temperature circulator YHX series are widely used in chemical, petroleum, medicine, biology, physics and chemistry, metrology, universities and colleges, electronic instrument, scientific research institutions, and other fields to experiment, testing and production of a uniform temperature controlled heating and place on the products of the test samples or experiment or test, constant temperature constant temperature worse control system adopts PID automatic control, LED digital display, its outer cycle pump can turn bad in constant temperature liquid output, outward second trough a constant temperature field is established.
YHX series low temperature constant temperature circulator provide - 40 ~ 100 ℃ temperature range of low temperature or constant temperature liquid, in order to meet the cooling water and the needs of the cryogenic liquid cooling or constant temperature instrument.Especially with the rotary evaporator (dish), fermentation tank, abbe refractometer, electron microscope, low-temperature chemical reaction kettle, biopharmaceutical reactor such as laboratory equipment. 

Main features:
Digital display resolution of 0.01 ℃, temperature fluctuation degree plus or minus 0.05 ℃ ~ + / - 0.02 ℃ is optional.
Closed compressor refrigeration, the lowest temperature can reach to 40 ℃ (80 ℃).Refrigeration system with overheated, over-current multiple protection.
With inner loop/outer circulating pump system, establish closed to the second temperature field or cooling container closed to the second experiment.
Low temperature measuring value deviation correction, temperature display precision can reach 0.01 ℃.
Using microcomputer intelligent control system, with functions of intelligent self-tuning PID control, digital display temperature.With functions of temperature measurement deviation correction, overtemperature protection, sensor abnormal protection function.Touch-key operation, convenient and quick.
When the tank adopts 304 stainless steel, clean sanitation, beautiful and corrosion resistance.
Optional second temperature sensor, aiming at the constant temperature field temperature temperature, start-stop refrigeration function to make the target temperature more accurately.
When the upper and lower temperature alarm can be set.
With W is horizontal, facilitate in super units
