Liquid nitrogen level controller

DADIAN LNL series small volume desktop liquid nitrogen level controller, the internal use of special circuit principle, specially designed to monitor the liquid nitrogen level position in real time, according to the measurement results directly drive the liquid nitrogen low temperature stop valve to start and stop, to achieve the automatic adjustment of liquid nitrogen content in the experimental container. In addition, it can also be controlled manually.
