Level Monitor Instrument for Liquid Nitrogen uses intelligent design with the functions of sound and light alarm, temperature display,  digital temperature adjustment, calibration .It is used for monitoring the height of samples in the cryogenic dewars and can send out alarm signal accurately,that is to say when the level is lower than the Sensor Lower, it will send out sound and light alarm to warn users to add liquid nitrogen. You can select the control part optionally for filling liquid nitrogen, stopped in scheduled time and the time for it is set by yourself  .

This product is shockproof, anti-interfered, reliable performance, high accuracy, long service life, easy installation, small and beautiful style.It is mainly used for temperature measurement of liquid nitrogen, liquid oxygen, cryogenic refrigerator equipments.
