Freezer thermometer with science and technology

With the development of science and technology, the human genetic code was slowly undoing. Frozen embryos is a kind of the world's only a mature method of preservation of reproductive function only mature. This technology is to get through in vitro cultivation technology of embryo, save 196 ℃ below zero in liquid nitrogen in the environment, save for a long time. Usually in the embryo and freezing liquid into frozen tube, after a slow and fast two cool way to make embryonic can still and can save in the 196 degrees of liquid nitrogen. In this technique, liquid nitrogen plays an extremely important role. It is inert, colorless, odorless, noncorrosive, nonflammable, and extremely low temperature. Although constitutes the most of the atmosphere, but it is not necessary to sustain life elements. In addition, liquid nitrogen can also be used in the food cold storage, metallurgical industry, cryotherapy, etc. Thermometer have also played a part, and, of course, the temperature of liquid nitrogen on it at all necessary. Square flange electronic thermometer is a digital display thermometer, compared with the traditional pointer thermometer, direct display, use more convenient, can let people intuitively understand how much he'd like to know what the temperature is. Its material is ABS shell, stainless steel temperature measuring head, thermal line length 1. 2 meters, temperature range for - 50/150℃, ℉, the accuracy is 1% ( - 20℃~50℃） With a resolution of 0. 1° C, the power supply is 1. 5 v button battery, easy to change, should pay attention to the storage battery, should pay attention to when using cleaning and inspection, regularly test the measured values.
