LEC Instruments Pty. Ltd. specialises in instruments used for assisted reproduction including microscope warm stage systems, incubators, liquid nitrogen level alarms, test tube warmers, warming trays and vitrification straws. These liquid nitrogen alarms are designed to indicate changes in liquid nitrogen or LN2 levels. Vacuum in storage vessels can deteriorate over a period of time causing LN2 levels to drop rapidly. These alarms monitor LN2 levels and provide alerts with audible as well as visual signals when the levels fall below specific levels. These alarms are set off when LN2 levels are below the sensors, when sensors have failed or power has failed during the fill operations.
These liquid nitrogen alarms are available in single channel as well as 6-channel models. The single channel alarms weigh 90gm and come with dimensions of 100mm L x 50mm W and 25mm in thickness. These alarms have relay contact with external buzzers through jacket sockets. The six-channel alarms have customisable sensor lead lengths according to the need of users and weigh 800 grams. These systems can be bench mounted as well as wall mounted for operation. LN2 alarm systems are provided with LN2 fill timers that prevent false alarms and disable the alarm outputs when not required. Alternately, these systems can be disconnected from the tanks during fill time.
