Uganda cryogenic liquid level sensor KGSQ liquid nitrogen level monitors

Liquid nitrogen sperm freezing tank is mainly used to hold liquid nitrogen and store frozen sperm. Liquid nitrogen is a cryogenic liquid at -196℃, which is characterized by easy evaporation; frozen sperm needs to be stored in a cryogenic environment at -196℃ for a long period of time in order not to lose its activity. When liquid nitrogen is held in a tank, with the change of time, the liquid nitrogen gradually decreases and the temperature gradually rises, frozen semen is in
